Some 64.6 percent of big supermarkets in Seoul make it far too easy for youngsters to buy alcohol, according to the Seoul Metropolitan Government.
The city government inspected the way 63 big supermarkets supervise alcohol sales from Aug. 12 to 20.
It asked high school students accompanied by university students to try and buy alcohol at a designated supermarket three times in a week -- during the day on a weekday, one weekday evening and at the weekend.
Some 53.4 percent of the high school students were not asked to show their ID card and had no problem buying alcohol, and 5.4 percent were asked to present ID but were able to buy the booze when they said they left it at home.
Some 5.8 percent were asked how old they were, but when they gave a false age they bought the alcohol without further trouble.
Under the relevant laws, those caught selling alcohol to minors face up to two years in jail or fine of up to W10 million (US$1=W1,119).
