Wow.... its good to vent....

I totally agree on the "If you have a seat, you should wait for standing people to get off first" etiquette.

The comment about not having anything to hold on to also applies to being squeezed in by the doors unable to reach the poles... but because of the squash, you can't fall over! So if everyone moved and squashed a bit more in the aisles as well, then no falling over there either!
