Need a Good Excuse
Going out to bars on the weekends to binge on alcoholic beverages and let loose is a major part of the South Korean culture because they work extremely hard during the weekdays. It seems like Koreans can get offended very easily if you don’t live life like them though. If you don’t want to drink, you’ll need to come up with a good reason.
Koreans may feel insulted if you decline an invitation for a night out drinking. So make sure you come up with a good and believable alibi that wouldn’t hurt anyone’s feelings. Of course, you should never drink if you don’t want to, but if you worked as hard as Koreans do, then that would rarely be the case anyway.
