I know most people are kinda critical about this and I'm sure I'd be ticked off also. But I can also say "Paybacks are Coming". I'd figure out something to do back to him. Hide a battery powered radio with a timer to turn it on 10 yards from his stand. Such as an alarm clock. So when it goes off he has to get down and find it and so forth. And when you hear it from where you're sitting you can just sit back and laugh. I'm sorry, but I can see the humor side of this.
