Firstly, he cancelled the 10am return time HE chose because of a meeting, then popped it on me that he was flying out that evening, which forced me to coordinate alternate return plans with my roommate whilst working on set.
Secondly, he tied down the gobo head of my C-stand ONTO the top of the arm in such a way that it was wedged on and wouldn't come off. When I finally pried it off all the coating had been removed to expose bare steel.
Nice guy, but was a pain in the ass and left my gear in worse condition than he received it in. Would not recommend renting to him.
