You guys would be surprised how much you can make as a waiter/waitress/bartender etc. Not to mention it allows for alot of socializing and possible networking.
That's my very last choice reason being that sometimes a waitress has to deal with a lot of stress/rude customers that believe they're the center of your universe and although I have experience in customer service I have yet to come across more than 2 people who have tried to disrespect me. I wouldn't be able to put up with it not even for the money.
