When is it racist behavior verses just bad service?
I've had terrible service in some restaurants, including very long waits for my food (> an hour in one case) and things like that. I suspect most people have had similar experiences. I chalked it up to crappy service and never went to those restaurants again. I refuse to spend my money at businesses that piss me off and I do indeed hold a grudge.
My wife is Asian. Quite often, she has wondered if some incident at work or in public is racially motivated. Sometimes, it might be but quite often it isn't. Perception has a way of becoming reality regardless of whether it's accurate or not.
