I'm sure passengers do some nasty stuff.

This does remind me of my least favorite aspect of flying coach. After eating with the tray table down, it usually seems like forever before the FAs come to collect the trash. I've been very uncomfortable waiting for this to get up and go to the restroom.

Just a thought, but may be a good idea for this "pig" delima as well. Ya know there's just really no place for trash. It's no wonder things get stuffed everywhere. What if the FAs when they distributed meals, snacks or beverages gave one small plastic trash bag per aisle seat and there was a little hook on or close to the aisle to hang it on. Passengers could put there trash in the bag, hang it on the hook and have their area clean to let them be free to move about. FAs could then move through the cabin to collect the trash much more efficiently by not having to gather each individual piece. It might also result in an easier plane clean-up.

Whadaya think?
