Most of the pistols are already broken and no one is repairing them. Wash the car, wash your head yourself. Sometimes there are no tokens for 1p and 2p coins, although there are tokens for pieces of paper (at least 5p). In winter, this sink is littered with snow, no one even cleans it here, either in snowfalls or after. There is no question about chemistry, the foam is normal in summer. But in general, it is clear that the owners do not care about this sink.
upd...
The price of 1.5 rubles is too much for this sink. There is no need to wash a brush or a rag. Although you can't use a brush here! See the photo)) But without a brush on the thresholds and disks, this chemistry will not wash the car without contact, no matter what anyone says. Water is constantly pouring from above at the posts.
