This story is cute:
A brand new cat club's very first show and there either wasn't enough rosettes or the rosettes were wrongly worded...a cat finalled and the owner was called to recieve the rosette. He took the rosette, saw that it was wrong one and started screaming at the judge in a different language to the judge. The judge was dumbfounded and the show security/committee took the owner away. The owner packed up his stuff and stormed out the show hall. 3 minutes later, his cat was called to final again! In fact, it was a four ring show and his cat would have likely to have finalled in all four rings!
The moral is: Be a good sport - show committees do make mistakes. Forgive them! By walking out, you may be missing the best day of your show career!
