The tipping service does not make any sense at all. All it does is lets restaurant owners exploit their waiters by paying them less than minimum wage and expecting the customers to pay the rest. As a customer we should only pay for the food. Why should we pay the waiter's salary? It is his/her employers job. You can say, "well, but you have to tip for the service." But isn't it the job of the waiter to bring our food from the kitchen to our table? Isn't he being paid for that? So why should I need to pay him extra? Then why don't we tip our mechanics, our doctors, our house keeper, the cashier etc.
