I mean could it be you? I agree the friendly, social aspect has died and been buried. But even I can go into the store and put on a smile and ask for things. I mean I despise the general public nowadays, but I also know how to interact without portraying that. I try to keep the the basic of ideas, treat others as you want to be treated. I don't get snarky unless they do, I don't EVER raise my voice or start carrying on like you see those crazy Karens do on youtube. I mean what does it achieve?
Not to mention, but I lived in Florida for about 10 years, and experience can vary greatly depending on what part you live in. If you live in a snow bird area, or tourist area, yeah you will be surrounded by rude a&%holes.
