over 30 years ago, I worked at FLAPS. I worked at 3 different locations in the same general area. One of them was a poor part of town. When I worked there, the older folks we on the whole, the most polite and down to earth folks you'd ever meet and a pleasure to work with. Some/many of the young folks (<25) were rude and obnoxious. On more than one occasion, I'd be having a conversation with a customer trying to get info so I could get them what they needed when a young guy would come in and try to interrupt.
"Hey man, I need a part!"
"Hey, hey, you need to get me a ____"

Nope, I did not deal with that. I was't rude, but I would tell them, "I'm talking to this guy who was here before you. When I'm done, then I'll deal with you," or something like that. They usually calmed down. They'd occasionally get irritated and even more obnoxious, but I would not budge. I suspect, although I don't remember any specific instance, that some customers may have said "go on and get him, I can wait."

When I see someone in a store/business being a twat these days, I often think to myself how wonderful it would be to tell them to STFU, but I don't get involved. It's up to the business folks to deal with problem customers. It might be different if the problem was essentially trying to take from me (as in the case of this thread).

I'm sure that most sheiße people are like that because it does often get them what they want because many/most folks don't want to deal with it. It's a shame more of them aren't taught the M Tyson lesson, "everyone's got a plan until they get punched in the mouth."
