I'm a little confused. I get the impression that your "laundrette" has machines for you to wash and dry your own clothes. But then you say that it comes back folded. How does that work? Or is my assumption wrong?

Also, the reason that people in the US do it is because laundromats are seldom close by (the closest one to my house, for example, is an 11 minute drive away), and often … scummy.
