Huh. I always thought it was the opposite. I know several restaurants that refuse to accept credit cards. They are great places to eat, but I won't go there. I don't think they miss my custom, though. Refusing to accept credit seems to be a signal of excellence, around here.
The cost of a credit card is very obvious. The cost of cash is many small things that are very hard to see and thus very hard to account for correctly.
For the same reason those food establishments had to get a government approved White Cash Register, because there was so much money disappearing.
* As long as you don’t raise any red flags in your accounting, which can be difficult.
I miss that. I really dislike that it is allowed to charge extra for a credit card. It shows that the company doesn't understand the cost of cash.
At one time, credit card companies forced vendors to charge the same, whether cash or credit, but that seems to have fallen by the wayside.
The problem is, is that cash is becoming less and less acceptable.
In a nearby town, you can't pay for parking, with cash. I have seen credit-card-only vending machines. A lot of restaurants have iPads at the table, and you never see anyone but the bus[boy|girl|whatever], bringing you your food.
