One of the pleasures we had during our time in North Carolina was a visit to the laundromat. The attendant was very helpful. Instead of making us buy a card to pay for the washers and dryers,which would have required a long-term investment we didn't need to make, she used her card to run the machines and we just gave her cash.
After we put our clothes in the washer, she said: "Now the good news for you, which is the bad news for me, is that I am required to stay right here on the premises. That means that you are not!" So we could go for a walk while the wash cycle completed.
I liked the sign on the washer that said it was forbidden to put human beings in the machine. Why in the world do they need to put up such a warning?
