After a month and a half of lunch duty, I have come to a realization. It is IMPOSSIBLE for people to walk up to a trashcan with out literally "throwing" items into it. People either practice their free throw shoot from 4-5 feet away or their underhand pitch from 2-3 feet away. NOBODY (I'm including teenagers and adults alike) walks all the way to the trashcan.
I've also come to the realization that there are typical reactions when a person MISSES their trashcan shot. People either 1) Follow through and pick it up right away, 2) Look around first to see if anyone noticed they missed it before deciding their next move, or 3) Pretend they never threw anything to begin with.
I have heard horror stories about lunch duty. But really, it's not as bad as I thought. So far it's an interesting place to observe human behavior - again, I'm including adults and teenagers. However, having said this, I reserve my right to change my opinion and decide it stinks at any time during the year.
