I worked as a waiter for years. At first when people would say "oh crap"(when mormons came in) I would get almost offended. After hundreds of run ins with Mormon families it is really hard not to start to despise them. You work 3 times as hard waiting on a family, house moms are literally the rudest customers on the planet, 10x as many custom demands, and even when you jump through all the hoops you get a 10% tip.
I for one hate the idea of tipping and wish businesses would just charge more for food and not expect anyone to tip.
