I wonder how much more expensive credit cards actually are? Cash costs money/time to handle and deposit, it's easily stolen, and easy to commit fraud with (like the classic move where a drive thru employee pockets the cash from a sale without ringing it up)
One issue I know smaller retailers sometimes have is that it can take a long time to get cleared funds into their account.
One small cafe near a place I used to work said it usually took 30-60 days for funds to clear into their account after a card transaction. That, for them, was a major problem as it meant that they couldn't then pay their suppliers in a timely manner when cashflow was highly variable.
Then again, a bakery I visited that was in a small town said they'd stopped taking cash, as they got robbed some huge number of times.
The computerization of order taking and kitchen tickets would seem to make it harder to charge a customer without ringing it up? I know you could cancel it in the system, but that's gotta be counted somewhere where a manager is going to see it eventually?
