I havent worked there so ill take your word foe it but i would imagine what location youre in matters a lot. Like if you are in a city in a low income neighborhood with a lot of drug users and drunk people i can imagine that being more difficult than some wealthy suburban location

Hard to say. Having worked at a few retail and fast food jobs in the past in varying locations you can get people that get it because they have a shitty job too and want to not add to the BS of your day understanding how it goes. You can also get low life scumbags that know they’re on or beneath your level but they’re off the clock and you’re on right now and they desperately need to grasp for some sense of power in life so take it out on the one person they currently feel above, at least in that moment of time. 

Then in the nicer areas you have Karen’s with shitty kids, but you also might get the soccer mom that is aware of her current privileges in life and is extra respectful and understanding with you and keeps the kids on extra good behavior. 

I guess the reality is you have the same thing either way, the customers either have awareness and are good people or don’t and aren’t. 

My experience was mostly low income to more wealthy upper middle class though. I never had to work or live in a truly bottom rung area with crazy amounts of crime, nor a super wealthy area where you see more luxury cars than not, so maybe my range of experience is smaller than I’d guess.
