Should we get rid of cash?

[Dr. Blackheart]

In the U.S., you can't add a surcharge for using a credit card.  I am not sure if that's the law, or part of the Merchant Agreement every bank uses with businesses that accept their card.

I don't think it's enforced that strictly, but once I was in charge of a large group theater outing where I collected money from everyone for the tickets and put it in the bank. When I went to the box office, I was told there was a $2 per ticket fee for paying with plastic.  I didn't have enough cash, so I paid the fee and called the credit card company the next day.  They immediately credited those fees to my statement, and my guess is that the theater got a chargeback and a nastygram from the card company.

Can't wait for my MU season ticket surcharge rebate!
