In one band I stopped using my better kit for gigs because while packing up at the end of every gig the guitar player would pull cables in a rather over-eager manner. Meaning that the metal ends (XLR etc.) would be flying through the air at high speed, hitting drums and everything else, often leaving scars on whatever happened to be in the way.
Before I picked up my Rock N Roller cart, from time to time I'd have a fan want to talk to me as I'm trying to load out. My trick was to say, "Hey, I'd like to keep chatting with you. Grab that case and follow me to the truck." In those situations, I tried to make sure it was the hardware case I was asking them to carry.
But this was all after everything was in its respective case and I needed to get gear to the truck.
Whenever this comes up I vividly remember this one helper named Mikey tripping over his feet and landing on and rolling over my bass drum. It was a long time ago, but still hilarious. Not then, but now, very funny. He rolled right off the front of it.
