I once had a Walmart employee follow me out of the building and start banging on my window screaming at me they're calling the cops

Why?

I, while using a cane in one hand and the other occupied by a bag of dog food that was making me regret not waiting for a scooter, didn't stop to chat with the old woman who was arbitrarily checking people's receipts.

I told him he's lucky I'm more level headed than most of my neighbors, because he would have been shot the moment he banged on glass and yelled, but if they want my receipt they can go watch the fucking cameras because I have somewhere to be.

Could I have handled it more calmly and with more understanding? Probably. But if you follow me out into the parking lot and start screaming at me, consider all respect lost, all decency dropped. You get back what you came in with.

Literally, the only reason I even went to Walmart is because the pet store I get the good food from had their registers all crash and wouldn't start back up.

Since when did Walmart check receipts anyway?
