The Barnes & Noble Experience

Oh yeah, there's also the B&N pervert. This guy writes the typical bathroom graffitti:

Be here 12:30.
I give good blowjobs.

But he actually shows up, and creepily follows any unsuspecting male customer who happens to have to piss at 12:30 into the bathroom.
Did I mention he drilled a hole in the partition between two of the stalls so he could 'peep?'

The maintenance people put a bolt through the hole, with metal plates on either side, to which he responded in permanent marker: "Was this really necessary?"
