Every number in Korea's floor-noise standard sits in one table. And a note under that table says the peak limit is only exceeded when it is passed three or more times in an hour.
Drunk Driving in Korea — Refusing the Test Costs More Than Failing It
What happens if you refuse the breath test? Art. 148-2(2) of the Road Traffic Act puts it at one to five years - heavier than blowing under 0.08%, and the licence is revoked with no discretion left.
Should You Go to the ER Over a Holiday? Korea Writes the List Into the Rule
What counts as an emergency symptom is set out under nine headings in Table 1 of Korea's Emergency Medical Service Rule - and one entry has the word "holiday" inside it: a child's fever over 38C.
When a Parcel Arrives Broken — Taking It "Without Reservation" Ends the Claim
Art. 146 of Korea's Commercial Act extinguishes the carrier's liability once you receive the goods without reservation and pay the fee. Damage you could not see gets two weeks - and a valuable is not covered at all unless you declared it.
Cancelling a Chuseok Train Ticket — Free on a Weekday, 20% Over the Holiday
KORAIL's penalty table has two rows. Monday to Thursday is free until three hours before departure; Friday to Sunday and holidays carry a minimum penalty even a month out. On a 100,000 won fare that is 5,000 against 20,000.
Chuseok Groceries — We Counted 74 Items, and 54 of Them Fell
The median retail item is down 7.2% on a year ago. Yet Singo pear is +24.9% and Tsugaru apple is −29.1% — 54 points apart inside the same category. It is not an average, it is a split.
Korea's Chuseok Toll Exemption — Three Days by Decree, a Fourth by Cabinet
The Decree names three lunar days. But item 3 of the same paragraph opens it to any day the Cabinet designates - and for 2026 that made it four, 24 to 27 September.
The First Gate Before a Korean Small-Business Policy Loan — Counting Staff Has Its Own Rules
A part-timer at 60 or more hours a month counts as half a person, and the measure is last year's month-end average rather than how many work here today.
When the Internet Is Down — 30 Seconds Tells You Whose Problem It Is
Put another device on the same Wi-Fi. That one check decides a 15,000-won callout fee — while compensation for two hours is 917 won.
When the Computer Slows Down — Money Enters at Exactly One Point
The first six steps cost nothing. Task Manager tells you whether to spend — memory high always means RAM, the disk at 100% constantly means an SSD.
When the Computer Shuts Off — Whether It Slowed Down First Decides the Cause
Heat cuts speed before it cuts power. A shutdown with no slowdown is probably not thermal — and that one fact changes both the document and the bill.
Blank Screen or No Sound — Three Seconds Decides the Bill
Press Windows + Ctrl + Shift + B; a beep means the PC is on and only the display is out. That result is what splits free from paid.
When the Computer Won't Turn On — Five Minutes Decides Free or Paid
Cable, 15 minutes of charging and a long press cost nothing. What splits the bill after that is adapter versus logic board — and the board is covered for two years.
Korea's Jobseeker Benefit — a 68,100 Won Cap, a 66,048 Won Floor, and Days That Expire After a Year
Only 2,052 won separates the cap from the floor, so doubling the salary barely moves the daily figure. And the year runs from your last working day, not from the day you apply.

There is still no provision setting a five-year point expiry. What we did find is where the law does speak — what happens to points after the term runs, and what changes at 50,000 won.
Unclaimed Insurance Money — the Three Years, and the Provision That Protects Them
Commercial Act art. 662 fixes three years and nothing else — not the start, not interruption, not inheritance. All three are in the Civil Act, and a bare demand buys only six months.
Unclaimed Money in Korea — Where “But I Got a Notice” Does Not Help
For taxes the statute says the period is not interrupted by a notice urging you to claim. For health insurance and the pension, a claim does interrupt it.
Korean Residence Records — “Only You” Applies to the Online Service, Not the Counter
The provision opens with “the person or a member of the household” and its proviso spells out delegation. The counter is far wider than the app.
Making Your Phone Battery Last — Half the Common Advice Is Wrong
We finally checked “a swollen battery is dangerous” against the regulators. The FAA restricts spare batteries to carry-on only, and the CPSC tells consumers to take swollen power banks to hazardous waste, not the bin.
What's Been Opened in Your Name — Lookup, Block and Alert Are Three Different Services
A ministerial notice defines all three separately. And name theft and name lending lead to opposite outcomes.
The Line an MVNO Has to Beat Is 75% of List Price, Not List Price
One sentence in the official guidance changes the whole comparison: the 25% discount is carrier-only, and MVNO users are excluded.
Cheap Flights, and the Refund Thresholds Most People Miss
US DOT rules: a 3-hour domestic or 6-hour international delay means an automatic refund, no request needed.
Booking Hotels Cheaply — and the All-In Pricing Rule Since May 2025
US lodging must now show the total price. And which card you use swings the fee fivefold.
One Degree Costs 7% More Power — But Up to 20.8% More on the Bill (2026)

Half of all laundry disputes come down to the wrong washing method. The right one is already sewn into the garment.
Stains and Discolouration — Why Soaking in Bleach Removes Colour Too
A third of Korea's laundry complaints are colour problems. Stains are decided in the first three minutes.
Washing Machine Care and Bulky Items — 90% of the Energy Heats Water
Per the Korea Energy Agency, 90% of a wash cycle's energy heats water. Dropping to 40°C cuts it to a third.
Foreign Payment Fees — Paying in Your Home Currency Doesn't Remove Them
The wording reads “foreign currency, or outside the country, or with a foreign merchant.” Switching currency leaves nowhere to escape to.
The Complete Packing Guide — Liquid Rules and Doubling Your Space
Five of the agency's 26 items are not objects — and one of them is your glasses prescription.
Beating Jet Lag — Light Timing Is Almost Everything
The agency gives only four numbers — three time zones, 15-20 minute naps, two days early, and a bedtime shift that reverses with direction.
Password Security, Properly — Two-Factor Authentication and Passkeys
“Mix symbols, change every 90 days” - the US standards body writes SHALL NOT next to both.
Never Lose Your Photos — The 3-2-1 Backup Rule
“3-2-1” is CISA’s small-business wording, but its ransomware guide keeps demanding offline, encrypted and tested backups.
Monsoon Mold — CDC Does Not Recommend Mold Testing
Because no acceptable-amount standard exists, a result informs no decision. Two numbers remain: under 50% all day, and dry within 24-48 hours.
Sell-By vs Use-By in Korea — 60-70% and 80-90% of the Same Limit
Korea's consumption date sits at 80-90% of the quality-safety limit; the old distribution date sat at 60-70%. Ten-day noodles: 6-7 days versus 8-9.
Korea's grade-9 civil servant starts below the minimum wage — on base pay (2026)
We opened the Ministry of Personnel Management's Pay Table 3. Step-1 base pay sits under the monthly minimum wage, and the largest step increase lands between steps 8 and 9.
