Read the link before posting would be a good policy, overall. The guy parked and then went to pay for the parking. Just in case this isn't clear to some, you can't buy a parking ticket for an illegal parking spot. The fact that he went to pay for the parking means that it was, in fact, a perfectly legal parking spot, provided you pay for it. The issue here is that the guy wasn't given more than a few seconds to pay, which isn't nearly enough time to do it in.
I honestly don't understand how some came to the conclusion that a car park of all places was an illegal parking spot to which he was somehow off buying a parking ticket for.
