Ok, so the toilets and sinks in the bathroom at work have those automatic sensors on them.
So I go to the bathroom today and the toilet decides to flush twice while I'm using it. Then when I actually step away it doesn't. It didn't happen today, but it has happened where I'll be standing at one of the three sinks holding my hands out just waiting for the water to start. Sometimes one of the other sinks will turn on either instead or in addition to the one I'm standing in front of.
Yay for technology!
