re: What would you do in this situation?

Yeah, and would have taken shorter rests too if it was someone who didn't act like that guy. But, here's the thing, he asked how long it would be so I told him how many sets I had left do about 6-8 minutes. He the demanded to let him workout in between, and stood there being a prick when he didn't get his way. Told him I'd be right back, and he immediately started using the rack as I walked away to go get the guy from behind the desk.
