In my country Venezuela the tips are not received by the restaurant, they are received by the innkeeper or as you call them, waiters. If the question was related in my country, then I would say that it is not worth getting rid of the tips because those are a great help for the complement of the salary of the innkeeper or waiter. In my country Venezuela the restaurant receives 10% if you consume internally in the restaurant, if you ask for the food to go, do not charge that 10%
