My wife and I just had dinner at Lisca, on Amerstdam and 92nd. The dinner was good. When I received the check, it was in an American Express embossed leather folder. I handed over my Visa card, thinking that if they didn't take Visa, I would provide my Amex. They came back and said they don't take credit cards at all. I asked if it said something on the menu -- they said it didn't, but that there was a sign outside. There wasn't anything I could find. Apart from being sleezy delivering the check in the Amex folder, not telling anyone about the cash only policy until after the meal seems underhanded and left, pardon the pun, a bad taste. What is the best way of communicating that you don't take credit cards? The couple percent that the credit card companies charge can't be a make or break for restaurants with $25 entrees (both of our's were). The only reason I can think of is to defraud the IRS. Are there any good reasons (for places like Lisca) not to take credit cards?
