What is a KTV waiter?

Mainly to serve wine to the guests and so on, and to clean up after the guests leave! Some guests will tip you if they have money, but some guests are in a bad mood, so you go and take it out on you. As a KTV waiter, you should be able to talk with your mouth and improvise, otherwise you will suffer. That kind of place is generally informal, and the good salary is high, depending on the individual.
