It would be great if they put a device for issuing coupons. And then during rush hours there is a showdown, no one knows who is the last, etc. According to coupons, everything would be civilized. At the Nomad car wash, they did it, the beauty is straight. I took the ticket and sat waiting, looking at the scoreboard.
I do not advise, it is not an economical self-wash at all, it is easier to give the car to a paid car wash, save effort and time, the same thing will come out for money. Although no, you can't wash it inside the car either. In general, it sucks.
