I see people walk out of the supermarket without paying constantly.

They just walk out with carry-baskets full of stuff, the staff call them out and they just keep walking with no consequences! They don’t even return the baskets!

Meanwhile, us honest people at the self-checkouts get treated like a criminal if we want to purchase something that is too light for the scales to register and are treated like social deviants if we don’t want to use a loyalty card.
