the vending machines at our school are crappy. they have a cafeteria worker who stands next to them so she can unlock the door and take out the thing you want when it gets stuck, which it does almost every time.
Technically, I haven't.
It's happened to me where the vending machine guy improperly placed the product into the machine, so that it didn't fall.
But I've never had a machine actually get stuck, meaning that the machine itself malfunctions.
Yeah You Are rite!
