You win the thread.
My office building also houses a university college, their classrooms, and their students. For some reason, students and staff come down to the first floor to use our bathroom, which is exactly the same as the other bathrooms on each of the six floors. Since the college and students moved in, we have experienced issues with people not flushing the toilets.
Two weeks ago, auto flushers were installed. So now, we have people hovering and making a mess, not cleaning up after themselves, and so on.
There is no one under the age of 18 in this building. This should NOT be a problem!
