Whale, yes it is possible that some sales could be slipping away from non use of quarters, but its like print advertising, you just never know what your actual return is from the advertising or likewise loss of sales from not taking quarters.
I think customers become trained to any wash on how to operate the equipment, like going to ARCO for gas, they have all those special rules to pay by CC or cash etc. Once you figure it out, your OK.
I'm up in Canada, as you probably we know we have the $1 and $2
coin (best thing that ever happened), if I were to take quarters, I think the customers would just empty their pockets of their quarters before using the $1 or $2
coins. Likewise with bills, I use up my change before using my bills.
I have two change machines that take
coin and bills for
tokens. For a $5 bill for example, I dispense $4 in
tokens and $1 dollar change. $10 bill, $6 in
tokens, and $4 change. I also have a CC to
token machine.
My start up is $2 for 4 minutes. I think in markets where prices are lower, taking quarters might make more sense to me. Also, if all your competitors take quarters - same thing. No real right or wrong answer. I am happy not taking quarters and dispensing
tokens. But I could always use another 5% business, who wouldn't.
