Well sure, anyone would. If you give me $20 on a $100 bill, and you were in my section for an hour with 5-6 tables that all had similar bills and tipping percentage, I'd be ecstatic! That doesn't mean it's a good system for everyone. Hot girls make the most amount of tips while dudes serving break their back to make 15%. That hot 20 year old server that you had last time you went out to eat goes to Mexico once a month on her tips.
