I found an original way for a bag of Peanut M&M's to get stuck in the vending machine.

When that bag of Peanut M&M's got wedged upside down into the complex door hinges, I’m sure that upset someone who wanted to eat those Peanut M&M's.  That someone spent $1.25 and did not get their bag of Peanut M&M's.

Those machine engineers who design these vending machines should have tested their machines to find those design flaws before they sold these machines to vending companies.
