1. I've seen it a couple of times but have no idea how real it is.
It's hard to tell these days. The abandoned storage unit shows seem totally fake to me. So do the pawn shop ones, especially the one from Detroit, and the towing shows. Mystery Diners seems legit, especially with the elaborate camera set-up, but it could be a re-enactment. Some of the employees the show focuses on are horrible...it's fun to watch them explain what they just got caught doing on camera!
