Men have disgusting habits in public restrooms. I worked in a convenience store for two summers, and in many restaurants and office buildings. The mens room always stunk in ways the womens NEVER did.
Y'all don't even want to know what the guys in my coed dorm did. THey replaced the carpet twice in one semester due to a group on one floor. THey also had to completely disinfect the stairwells from basement to the top of our 14 floor dorm building. The guys would go and see how far down they could make it wtih just about any bodily fluid they could get out of themselves. It was so bad with a group that started as freshmen the year before I did that we had written notice from the EMTs and fire dept that they would NOT be going up and down our stairwell because of the risk of infection, so we better pray for the elevators to work fast. I wish I was joking.
In high school I worked in a used bookstore. We did NOT accept trades for playboys, etc..., so some of the guys would try to pick up a copy and take it into the bathroom with them. Sometmes they left it there, other times they put it back. I flat out refused to touch them, not to price them, to accept them, to bag them up after a sale, nothing. The little old ladies I worked with at first would go back and ask the guys if they were 'okay, not constipated or anything? Do you need some prunes?" That did apparently deflate more than a few of the men, thankfully. Then their granddau started running the store and she bought a big thing of plastic wrap at sams and she would wrap them and seal with duct tape. I was never more thankful for duct tape and plastic wrap in my life!
We generally have a book or six in the bathroom at home. J is really bad about keeping a stack in there. Always was, even as a toddler. But that is our HOME. I have NEVER seen someone take a paper into the bathroom at work, read it, and put it back out for others to deal with. EEEUUUWWW!
Of course I think it is disgusting to save the cardboard roll from toilet paper for crafts or whatever too, so maybe I am a bit off.
