Have you ever been charged an additional fee because your dog was a PITA at the boarding kennel?

My dog spent the weekend at a local professional show breeding and boarding kennel while I was out of town. Usually he's boarded at a kennel specializing in police K9 training, and the people there love him. "Mrs. B's breeding Kennel" was the only option with space available on short notice. He's stayed there a few times in the past also with no problem. She informed me when I went to pick him up that he "lifted his leg on everything" and incurred an additional $25 charge for doing so. I asked if he'd somehow gotten loose in her house (although he's NEVER done this in any home he's visited). No, he'd done it in the kennel. Male dogs typically do mark new areas, especially when there are females in season around. All that would be needed is the usual hosedown normally done anyway as a normal part of kennel housekeeping. Have you ever been hit with a charge like this, and do you think it was reasonable?
