It keeps your quarters on site instead of them walking off to fill other people's uses, such as a laundry mat, collectors, poker games, or whatever else people can think of. When it's not certain you will get cash for cash, the person using your changer is (more) invested in your car wash.Why mix quarters and tokens?
I know you know this, but if you're anything like me it sometimes takes a ball bat to see things differently from what is currently working well.It was either that or buy at least $500 in quarters twice a week. I pay $535 for a bag.
I've seen several here taking pictures of my signs and using a translator app so they can read them.Believe me, if I had customers that I could communicate with or had real problems with break-ins I'd most likely do that, as well as offer bonus tokens when they buy more than one. At least 70% don't speak English at all, and I'd guess 20% of those who don't speak English can't read at all.
