I've been to PHOF dozens of times through the years.
On various occasions, I would approach Tim to say "hello" or ask a question. He has always been respectful and friendly to me. I don't bore him with my pinball history, nor do I ask him dozens of questions. When a machine malfunctions, I let him know and continue playing other games.
The man just doesn't suffer fools. After all the years he's run PHOF, I think he deserves that right.
