This actually happen to me in real life.
I was in the mood for some chocolate milk so I went to the vending machine, but I never got my stupid chocolate milk.
1st day I got the wrong thing
2nd day, lost my quarter
3rd day the cost of the milk went up 15 cent.

there was a 4th day, and the stupid machine wouldn't take my dollar.

it seriously felt like the machine had something against me. lol
