I lived in on-campus student housing that had bathrooms like this (the locks on both sides of both doors version.) My friend was in the bathroom during a commercial break of X-Files and I locked him in there. Ha ha. So he knocked on my neighbour's door and got out that way, but he still needed to get back into my room from the public hallway. I was watching him through the peep hole in my door, and to taunt him I opened the door and quickly closed it again. The two problems with that were that the peep hole made it look like he was further away than he was and the door had a hydraulic arm on it and didn't close as quickly as I expected. Anyway, I put ice on my forehead for the rest of the episode and then went to the hospital for three stitches. I'd say that the likeliness really depends on whose bathroom it is. ;)
