Good cheap entertainment: Stand by a full trash can / compactor in T2 at JFK.

Some people come up and are already resigned from cancelled flight after canceled flight - producing a look like, "Even the trash can won't take me."

Others come up and ask after pushing at the door, "What is this thing?"

The most entertaining are those that have reached the boiling point and start shaking the can like a pinball machine as they mutter to themselves.
