Answer:
Waiters should not have to tip other tipped employees. Those employees have to work together. Usually they will split things up, they should work as a team. Waiters should tip out busboys 10% of the tips made that shift.
Waiters should tip out the bartender less because a bartender usually makes as much, or more than the waiter does. It is common to tip a bartender according to the amount of mixed drinks they have to make. If you had a busy night, but did not order very much booze, than usually the bartender is cool. But if you have a busy night and order alot of mixed drinks, than you better pay the bartender half of what you give the busser.
Bussers should be tipped out everynight.
