I know what you mean!
Going to the meat section in the grocery store is a bit scary nowadays. The carnivores come in hunting and give you looks like they will run you over with their carts if you don't get out of the way fast enough, or if you pick up too many steaks. I have a carnivore to shop for waiting at home (mom) so I know I have to fight for those steaks, or else.
IMO, it was Covid that prompted the change. People got used to fighting for TP and it carried over into everything else.
Walmart really is the worst. I have a better experience shopping at Publix. But at the Dollar General before the hurricane, people were mighty cranky because there was only one checkout open and a dozen people waiting. One lady found an employee on his 5 minute break and we could hear her berating him from inside... swearing and stuff, she basically heckled him inside. I wanted to say something to her, but I've learned my own temper can make things worse so I did my best to keep my mouth shut. It's not like we enjoyed waiting, but geeze, you don't know what a person's day has been like. He could have been home making his own preparations for the hurricane.
