A term used by people in the service industry for difficult customers who leave little to no tip. This term is often used for African Americans, and Foreigners, including actual Canadians, that tend to act like they do not understand the American system of working for tips and getting paid next to nothing hourly!!(which is how the term started) In countries other than the USA waiters get paid hourly rates, and tend to not receive tips so, when they travel to the USA they either don't know they should tip, or pretend they don't know in order to cheat their server. Unfortunately African Americans tend to also fall into this category of incredibly low insulting tips or just no tips at all.
Man, I'll never be able to pay rent, or feed my kids if I keep getting all these tables of Canadians not tipping me worth crap! I mean I'm not here waiting tables for free!! :-(
