I left a silver dollar as a tip at a restaurant
What made you leave a silver dollar as a tip?
I'm trying to get the waiter noticed by the restaurant manager to get a promotion at work.
Tipping is not mandatory in the United States, so there are no laws that govern how much gratuity should be paid. That means it is generally up to you to decide how much of a tip to leave a server at a restaurant.
Well since it's not required, then the silver dollar is more of a bonus to please the waiter.
Well that is good you were able to tip them. You are expected to tip people for good service. I hope that you enjoyed your time there and were able to help out the waiter.
