Min wage increase would make your food more expensive b/c of the back of the house, not the servers. Point is, you are paying the unskilled labor double the skilled labor because of an outdated tradition and it is inflating restaurant prices in general. The hilarious thing about it is that tipping was instituted because restaurants were abusing young single women. To support the fact that 15-20% of a restaurant's income is walking out the door (usually waaay undertaxed - servers only claim a portion of tip income generally) owners are forced to make that up by paying as little as they possibly can to the poor guys that actually make the food and do the real work. But they are brown and out of sight so who cares.
