I know I say a lot of bad things about Bethel, but one of the things they teach the new boys is to tip properly. They said that when figuring if you can afford to eat out, you should always factor in the tip. So if a meal is ten bucks, in your head it should really cost 12.
I am always afraid to eat out with JW's because they are horrible tippers. On several occassions I've had to give the waiter a few extra bucks to cover the poor tipping. I apologize to the waiter for my 'friends' behavior. Even after ou explain WHY tipping is important, the friends usually give an excuse that boils down to 'i don't want to give them extra money.' Fuck em
