Murphy's Laws on Vending Machines

Vending machines only contain edible material when you are not hungry.

The person in front of you will always get the last one.

If the vending machine actually has what you want, it will cost more than the amount of change that you have.

Anything you purchase will get stuck and hang on the edge of the rack.

If you only have dollar bills, the vending machine will reject them.

There are only two times when vending machine operators appear: when you kick the machine in disgust, and when you try to shake the machine to make your stuck snack fall.

Vending machine operators will never have a sense of irony or humor.
