Standing in line behind 7 or 8 other people, we had ample time to watch the thing in action. Normally the charge for parking would be 4.50 or 8.50 and people would slip in a 5.00 or 10.00 note. The machine could and did spit out 1.00 notes in return, and .50 coins. It did this for the first 6 people, slowly but not maddeningly so. To be fair, the slowness of the machine was easily matched by the time wasted by the idiots who consistently waited until they arrived at the machine, slipped in their card, and read the amount due before it occurred to them to even reach into their pockets or purses for the cash. But I digress.
Customer #7 arrived at the machine with a 50.00 note. Possibly he had nothing else, but since the uncharitable view is always more amusing, I think he was simply flaunting his wealth, or appearance thereof, by implying he had plenty of money, of which this was the smallest he would deign to carry.
I had no doubt, and I wasn't giving it the opportunity. We put in exact change. Now it was the machine's turn to say "WTF?!?" After which we could clearly perceive it also humming angrily, "How am I supposed to cause any trouble with this? It's not fair! Come back here, you!" But by that time we had run halfway to the car, safely out of range of the EMP that the machine must surely have beamed after us in spite, trying to short out our mobile phones...
