Another sign of the US becoming less civilized is restrooms are locked or not available for customers at many stores now. Went to a Safeway in a different part of town the other day, and had to use the men's room. I asked one of the employees collecting carts where the restroom was and he told me to use the employee restroom up the stairs because the other restroom is locked and it's too much trouble to unlock it. So I did, and then continued my shopping.
About 10 minutes later, the store security guard, this short chubby Mexican guy came up and started interrogating me about why I went into that area of the store, lecturing me about how I'm not allowed back there and making a huge deal about it. He stood there going on and on for several minutes, even after I told him what happened. He finally left and I went about my business.
I finished shopping and went to checkout, of course no human cashiers, only the robot stations, and the same guy stood behind me looking over my shoulder the whole time watching me scan my groceries.
My patience had run out with the guy at that point. After I paid, I said to him "Take it easy there, Robocop.", and the guy immediately flew into a tantrum, started yelling insults and whatnot. I just walked out with my groceries. As I'm loading up my car I still hear him yelling from across the parking lot.
Something happened in 2020 with retail employees. Many of them stopped trying to be helpful and polite, and started being adversarial. They can't lord over people with the mask stuff anymore, but the same attitude remains. It makes what should be a simple task like buying groceries into a bizarre and unpleasant experience.
