I love the transition. xD As soon as he said "push the button to get your snack," I thought, "yeah, sometimes..." Lol. And then he immediately went into the bit about snacks getting stuck.

In my previous school you had to push and kick the machine from the side if something got stuck

Back when I was in highschool one of our snack vending machines was kinda terrible and some snacks would get stuck (cheezits were one if the biggest culprits).

Fortunately my arm was both long enough and thin enough that I could reach up and pull the snack loose. My friends quickly learned that if it happened to them to come look for me to get it out for them.

When I was a kid, I would smash nickels with a hammer till it was the size of a quarter and take them to the arcade. Believe it or not, it worked every time 🤫

So what your telling me is that the vendor at the market turned of the sensor that tells the machine the food made it to the bottom.

So to save anyone's time..
The machine uses a Laser to detect coin width.
Assuming counterfeiters got the faux coins width incorrect

Always put real cash/coins into the vending machine.

What an imbecile. No one should ever put fake coins into the vending machine.

I wish the vending machines at work had these light beams. Lol I'm surprised they still function after all of the shaking they go through.
