At one of my sites, we had an issue with people parking in the fire lane. Eventually, the city got fed up and sent the PD to crack down. One lady got a ticket and immediately came to howl at security because it was just a few minutes! And we needed to fix it.
The best part was that the cop who wrote the ticket was still there, writing more tickets. She walked right past them to get to us. The cop turns around, and writes her another ticket.
When she got back to her car, she howled and demanded we write a letter telling how it was OK for her to park there and how it was only for a few minutes.
Oh, and of course, how she was never coming back.
The real kicker: we had a parking garage where the first hour of parking is free.
May your custies be smart, or actually follow through on the never coming back promise.
