Well, as the lady that owns my favorite cheese shop is thinking of going cash only. She is paying $5,000 a month in credit card fees.
I just don't see the costs with cash. That article makes no sense. But it is from a bank, which makes nothing on cash business, and 3% on credit card sales so not sure they are unbiased.
I used to have to count out a cash drawer every night, took 5 minutes. Although most of the places I go to that are cash only are like the cheese store, and the local gourmet hamburger restaurant where the owner is the only one in the cash drawer, so there is tight control over who gets in the cash draw.
