I bought a small toy for my son the other day that cost one dollar. I didn't have any cash on me, so the clerk offered to take my credit card. He said they they had no minimum. He also told me that most stores these days have no minimum, and that he and most everyone he knew didn't carry cash most of the time anymore.
Is this no minimum thing affecting street performers? When you pass the hat do people have no cash in their pockets?
