When one of my shoots involved the 'talent' being a jokester while I was operating, I stopped, removed the gimbal from my vest and handed the rig (with a 22lb camera on it) to the guy. Fortunately, he was strong enough to not drop it. A first hand look at how heavy it was ended any more fooling around like that on the shoot. (BTW: not my rig, not my camera, fully insured and a government worker with job security)
