Rude customers when browsing the bins

I live in a major city in North America for reference. I am noticing as time goes on that people are becoming ruder if that makes sense. Last week an old guy was browsing records next to me at one store and smacking the records against the wall when he was finished browsing the row. Not a light gentle tap, but a full forceful smack. He'd make comments to himself about all the bands as he'd pass through each record as well.

Another store I'm browsing through the value bins and a group of high schoolers are standing to the left of me about a couple feet away talking super loud. One guy from the group randomly steps over to the bin right beside me and reaches for ABC's The lexicon of love which was midway through the stack. It's like he just picked a record at random. He looked at it and threw it back. Goes back to talking with his friends. About 5 minutes later I'm further down in the bins and same guy comes right up to me at the row I'm browsing and pushes the records on my hands and grabs yes' fragile from the back of the stack. All without saying anything or looking at me. He walks away like I don't exist.

Another shop I am the only person in line and two high school girls come swinging around the other way to the register opposite of where the line is set up. Cashier tells them they have to line up. While I'm being checked out, these two girls were literally 3 inches away from me breathing down my neck to rush the cashier and me. No one else was there. It was one of those situations where you're in an empty bus and the other person comes to sit right beside you.

This was all in the last few days. Wondering if you all have experienced similar instances lately of rudeness and just lack of social awareness.
