The first type are the worst. Encountered one of those the other day when shopping. They just left their shopping cart next to the conveyor belt at checkout, literally blocking me from pushing mine forward so i could load up the belt. I nudged it a little, but they didnt react. Then suddenly, the cashier asked if a jar of peanut butter at the end of the belt was theirs. They were like “oh, yes it is”.
I thought they would grab it and also see that they left their cart in my way, and move it. Nope they grabbed the PB and handed it to the cashier, finished checking out, and left with all their shit in bags, sans cart. Absolutely ridiculous!
