Everything is fine. But I do not understand why, at the time of writing this comment, in 2019, we did not add the possibility of paying by card?
Cash only is not very convenient.
I wash my car in 4 minutes or less, but I can't pay less than 5p.
These car washes have very low flush pressure. Because of this, the car remains dirty or you have to rub the chemicals with a rag, which automatically increases the cost of washing.
Great car wash! Chemistry efficiently removes dirt from the car. You can pay with a card!
Cons: there are often huge queues and an inconvenient timer, I can't figure out how much time/money is left.
