It’s pretty well-known in the bar/restaurant industry that blacks are bad tippers and often won’t tip at all if the server is white.
Servers mutter curses under their breath when they see a black family seated in their section knowing they are going to get little or nothing for their effort. This, in turn, causes servers who know what’s coming to provide poorer service which the blacks then perceive as racism when, in reality, their reputation is what brought out the bad service.
So it becomes a vicious circle - blacks tip poorly so they get treated poorly so they claim racism which only leads to more bad tips and more poor service. One place I frequented tried to remedy this by having black waitresses serve the black tables but the black waitresses got fed up with the crummy tips as well and quit.
So what does an establishment do? They can’t have a “no blacks” policy because that would bring out the Jesse Jacksons and they can’t lecture the blacks on the proper way to tip or get the r-word thrown back at them. It’s a no-win situation just as stores in bad neighborhoods often find out as well.
auto-tip is not a tip
They should just incorporate it into the price and raise the pay of the wait staff. This tipping vs not tipping is stupid.
Pay your own dang waiter or don’t open a restaurant
A year or two ago at Texas Roadhouse we had a group of young blacks sitting near us. They had over a $100 bill. After they left the waiter told us that we had tipped more for our under $40 meal then they did for over $100 meal.
