We use full rolls to pay the petsitter. Does she deposit them in the bank? I expect not because she frequently emphasizes that she prefers to be paid in "cash".
I also have paid our petsitter with dollar coins as she does not take CC's. I did ask her if it was OK to pay that way first. She said "Sure. The kids use them for lunch money". I'm sure that will continue to be Ok for a while and as long as our bill is around $25 or so but I'm sure there would be an issue with more than that.
