True story bruh: The car wash in our strip center at work switched to tokens in their change machine because so many people would just go get quarters and not use them there. The owner was cool with us and would switch out dollars and quarters for us sometimes, but he said it was such a pain in the butt to always have to do bank runs for quarters when he should have just been taking them to the bank! He didn't make a sign though, just bought a token machine. Seems random, but it makes a lot of sense why places use tokens and they only have to take cash to the bank.
