A Reddit user created the thread on the "FragReddit" subreddit. The top comment refers to the cashiers, some of whom have to endure a lot in their shifts.

The post creator himself also revealed what bothers him most about the supermarket checkout. He immediately had a suitable answer ready: "Well, physics is difficult." The post led to a lively discussion in which other users described their experiences at the checkout.. If it takes a little longer at a supermarket checkout, it is usually because there are too few checkouts open or there are problems with payment.
