Two weeks ago, I stopped by a Dollar Store looking for nice winter gloves and some other small items. I wandered the store, picked out several things, and brought my choices up to the counter.

The cashier rang it all up, and I offered them my PayPal Debit Card.

"Sorry," he said, "we don't take credit cards."

This happened again at another small store of the Dollar variety, and then at McDonald's. In this day and age, what business doesn't take credit cards? Our business is in the middle of the application process for a merchant account, and we accept them via PayPal.
Cash has been earmarked for non-traditional transactions (garage sales, thrift shops), but buying gas, food, sundries -- that all gets taken right from my account, no worrying about if I have enough in my pocket, no waiting for checks to clear. The only rare times we write a check are for bills, but most of those are paid online. The way the world of instant transactions is moving, who knew that businesses can still operate on a cash-only basis?
