I used to be a waiter on Mackinac Island Michigan. We always hated getting Canadian or European customers as they rarely tipped anything. We also hated getting a table of old ladies for the same reason. There were very few blacks visiting the island so I can't comment about how they tip as a group. The manager of the restaurant definitely used table assignments to reward some waiters and punish other waiters. The waiters had to share a percentage of their tips with the bartenders but otherwise tips were not shared between waiters. Tipping has many drawbacks but I doubt waiters in the US would want it eliminated given how much money they can make when they get a good tipper who drinks a lot of alcohol. That makes up for a lot of bad tippers.
