I was a small business owner for 15+ years and we never took debit or credit cards. Our average sale was under $5.00 with very low margins. Most people were very understanding and we only lost one sale over that policy. That one sale certainly would not have made up for all those proccessing fees.
I tend to pay cash for my quilting "needs", but credit card for other things because of the cash rewards.
I hate that cursive is going away, but schools should be teaching for the present and future worlds, not our nostalgia. Sadly.
