I had a ref get mad at my asst. coach one time for not having the names written on the weigh in sheet in advance (for the record they were, he turned to the wrong page) and about half way through weigh ins, he kicked us out, told us to get the whole team reassembled and we had to weigh in again at the end of weigh ins. Needless to say half my team missed weight and we got steam rolled. We never went back to the invitational again.
When I was competing, we were at either Tournament of Champions or AAU Nationals and we had one kid over weight. We are all miserable from cutting so after we weighed in we left the kid there to keep cutting and we took off to eat. When we returned our coach had him check his weight and he had gained weight. He told our coach he got a drink of water at the end of every lap he ran b/c he was thirsty. Hahaha.....
