At least your owner was nice. Biggest shop I went to in Pittsburgh (Pinball Perfection), the guy was very rude and didn't give me the time of day, had tons of games in the shop but wouldn't bother showing me the warehouse. This was after telling me on the phone to come down and check it out. The other shop owners badmouth him (I can see why), he's overpriced and doesn't know how to treat customers.
Actually he might only be tied for the biggest in Pgh, Greco Amusements is where I got my Pac cab and he had probably as many. It is sad and odd seeing so many unused machines though, especially when they are arranged like a huge, silent arcade. Like an arcade graveyard...
