I ran into a weird situation a few days ago. I parked in a parking garage and when I later went to leave the pay machines were marked "cash only" because their credit card processing system was broken. It turned out to be moot because the clerk at the desk agreed to process my card, but the clerk was threatening to not process any more cards and there was a long line behind me.
When I went out of the garage there was a sign right at the entrance saying that they accept credit cards complete with credit card logos. There was no "cash only" sign at the driveway entrance at all.
So, if the staff refuses to accept credit cards and somebody has no cash, and they kidnap the person's car what is the legal remedy? Is that criminal conversion? Can you sue them? If so, who do you sue, the clerk, or the owner of the garage, or both?
