Used to work in a supermarket. The non-whites were the worst bad customers by far. Whites would initiate bad interactions, but would usually settle down if you were patient with them. Muslims would treat you badly no matter what you did for them. Even if you went along with their every ridiculous demand they'd still look at you like shit. If you refused, it would be another report of 'racism' to the management (who fortunately ignored them). They were especially fond of threatening female staff. The influx of Muslims left no-one with any doubt about how bad they are. Chinese would largely ignore anyone who wasn't Chinese, but were notorious for stealing. One old Chinese woman actually came back in a terrible disguise after getting caught and banned. Very few black customers. One literal Abo once. She kept picking up random items and presenting them to me to be reduced and no matter how many times I explained it's based on the date, she couldn't seem to understand. I have no idea how she got there.
