Gum Chewers

It is socially unacceptable to put your hand next to someone's chin and say "Spit out your gum, now, please."

I reminded myself of how socially unacceptable this was when the gum chomper next to me was determined to drive me off the train.

There are worse things, I suppose...but gum chomping at 7am is pretty bad. If it's loud enough to be heard in a crowded train...you are chewing too loud.
