it's something cultural.........even with the very wealthy. I have no idea why either.......i would think of all people, black people would appreciate a hard working lower income position that relies on gratuity. I know a gtirl who bartended one of lebrons parties..........made almost nothing...........ev en served lebron himself multiple drinks and got $0 from him. oh well, i tip the homeless.......blacks included, so they can do what they want...
