Only problem I've had with it came from a shoplifter, and it was probably less to do ith general racism and more to do with the fact I'd just said to him I was sick of scum like him coming in and treating us as though we were even half as stupid as him. Oh, I was once accused by someone of being racist as well. Unfortunately it wasn't a formal complaint, because I'd have quite liked to see how a disciplinary procedure would go when the accusation was that I was being anti-English.
