Oh, and a personal thought:
why is everyone so obsessed with "their" bin?
Often I have to persuade passengers to go one bin up, or down the aisle, that bin still being almost empty.
I can understand people wanting their stuff somewhere close, but come on, what's wrong with the bin on the other side of the aisle, when you see someone sitting in the seats already and there's still space to be had?
"But I want it in my bin!". It's not your bin, it's the bin closest to your seat.
Okay, rant over.
