Ok, I just can't believe that no one seems to care about the cleanliness of the bins for security. Ok, here's what I noticed on a recent flight from PDX to LAX, it's disgusting:

1. Guy put his shoes in the bin with dog (or cat) crap on the bottom.
2. Hairs of questionable origins in the bins
3. Some sort of goo in the bin
4. Gum stuck in the bin

So I told the TSA supervisor... that worked well, they didn't seem to care. Honestly I'm just curious how many viruses and crap are transfered this way. In fact I would bet that the bins are more dangerous than the actual threat of liquid explosives.
