Well, here's a story of something potentially gross that happened today. Be warned there is mention of diarrhea and toilet splash-back...

This is a suggestion that I had sent to my college's suggestion box:

"Hello. I think that the automatically flushing toilets in the public restrooms are a great bother. They can potentially raise the water bill of the facility.

Did you know that earlier today, while I was having gastrointestinal problems, the toilet kept flushing at undesirable instances? It flushed 3 times before I was able to let anything out(whilst sitting), and 2 times mid-way(and it simply isn't pleasant to feel the splashes of waste-water on your bottom as it flushes underneath you).

What's more, after I finished my business and raised my bottom just slightly to wipe myself, the toilet simply flushed right there(wasting another of the 3 toilet seat covers I had to use), before I was given the chance to throw the toilet paper into the toilet. After it flushed, it took quite a few minutes to get it to flush with the last bit of toilet paper left in there.

These constant and repeatedly unexpected flushes of the automatic sensor toilets are more than likely to raise the water bills. I have formed a phobia of these automatically flushing toilets over the past years that they have been in public restroom use."
