South Korea takes respect to a whole new level so if you are travelling to South Korea and don’t want to offend your guests you better listen closely. Besides the popularity of Korean food throughout Asia, South Korea is also known for its affection for the not so occasional drink. Not so occasional as alcohol is seen as a party starter and a way for people to loosen up and have fun but even with fun in mind don’t forget to put both hands on a bottle when serving or pouring for those older than you!

This is a sign of respect regardless of whether or not you have had a little too much to drink. Holding the bottle and serving with one hand is strictly for the elderly other than that drinking is an all night affair so enjoy next time you are in South Korea.
