that's not the point at all. it was merely an example, borrowed I might add from what other posters have already contributed for as long as I've read this forum.
a customer looking to buy a bun is not looking for a racial judgment. She's looking to buy a bun or three. If she wanted a debate about poondekness, she would come here. if a person is hired to take care of customers by selling them stuff and she's offending them on the job instead, shouldn't that be sackable?
If that customer is taking a job that should have been for sinkees, then that customer deserves the worst treatment sinkees can give to her.
