Nobody probably notices this stuff but me, but I am an architect and I am pretty observant. And I am probably partly crazy. Oh and I spend a lot of time in public bathrooms. Ever notice that the only place you see non-reversing security screws are in public restroom stalls? Probably not. But I am guessing people want to be most destructive when they have a few minutes to just sit and relax and tamper with things; and bathroom stalls are their favorite things to tamper with apparently. "Just sitting here with my screwdriver... might as well take apart this stall door."
Check it out next time. I've never seen these anywhere else.
