Did I tell you about the time that I charged a 39-cent Big Gulp at a 7-11? (Some years ago, obviously.)

And the guy hadn't ever done it, so he pulls out the old credit card imprint machine, and nearly puts a "REFUND" slip in the machine instead of a normal slip! I would have been paid 39 cents on my card to drink the gulp!

Of course I stopped him. But I think that sets the record for minimum charge on any of my cards.
