For several months, we had someone pissing on the floor of the men's room. I work at an engineering firm in the suburbs, these people all make $100k+ and most are senior professionals. I don't know if they found him by figuring out badge swipes (he hit a lot of bathrooms) or if he just stopped on his own.

It's also entirely possible it was mass hysteria. Sometimes people miss the urinal and maybe some did it to be funny after the signs went up.
