Are there any self-service carwashes near you?

There used to be two of them near me and now they are both gone. I wonder if the franchise went under.

If you don’t know what I am referring to, the self-service carwashes were a bare bones operation that cost about half of what a regular carwash charges. They could handle up to, I believe it was four, different cars at a time in separate car washing bays. You would purchase tokens from a machine beforehand. Each token allocated a certain amount of time. There was a dial that you could use to divide the time up into the various stages of carwashing, causing different things to come out of the hose. Then you just walked around the car spritzing it with whatever was coming out of the hose and changing the dial whenever you wanted to move to the next stage.
