This vending machine was not kind

Not with the double-flap doors that most vending machines now have!

I suppose you're right, but this machine doesn't look completely new. It's a bit rusty/dirty/whatever on one side. It looks like an older model to me, but then again, I'm no expert in vending machines.

It's okay. I've spent my whole life applying mechanical logic to almost everything, plus I've spent too much money buying things from vending machines. But on the plus side, if someone could shake this machine just a little, it may dislodge the obstruction. Catch-22, If the red bull dropped,they would have enough energy to do so.

Fair enough.
