I think it's safe to say that most of you don't like public restrooms. But, I've never given much thought to what's on the other side of the wall, although, holes in the ceiling give me the creeps. I will admit that any humming I've heard was easy to identify as coming from another human being in the stall next door—these guys can't say that!
I've worked in some small spaces before, but geez... :) So, the next time you hear a gentle hum from the bathroom wall, don't be so quick to call the X-Files.
I can't help but wonder what happens when a server goes down and the stall is occupied?????
You know these guys have got to hate this..."You think you've got it bad? My office is a real crapper!"
