Men who don't flush public toilets

[Fireball]

Truck stop bathrooms are the worst I've ever seen. And oh, those auto-flush toilets waste huge amounts of water, often flushing several times before you ever finish.

Put a piece of toilet paper over the sensor. My cousin's grandkid got freaked out when the loo flushed on him back in the day, and we figured out a fix. The kid made a big deal out of covering the "eye" for a few days.

I discovered the tissue trick a few years ago. Nothing like having one's junk sprayed with fecal-matter tainted water. A "nice" feature of the auto-flush sinks and toilets is that when the battery fails, the valve goes wide open. I went in to work one Monday morning only to hear a toilet running full force in the lady's room. The thing had probably run all weekend. No handle to jiggle, so I took a piece of stainless steel bar left over from a tool I designed and tapped gently   on the valve until it stopped, and then called maintenance. They replaced it with a flush handle. The plumber told me that it was code on new construction to use the auto-flushing stuff to save water, but they were worse in the long run, so they replaced them as they went bad with conventional hardware.

Squat toilets. I saw my first one in Turkey and a number of them recently in China.

At one of my company's buildings, the engineer not could figure out why half empty cups littered the women's stalls. Apparently, the east asian women who worked in the call center had a different method of cleaning their bottoms.
