Gambling Vending Machine

It’s said that money won is twice as sweet as money earned. Unfortunately (with few exceptions) people don't eat money. However, people do like to eat food. And I can personally attest that on those rare occasions when a vending machine mistakenly gives you two mars bars or two cans of coke, the free extra one does taste much better. However such events are far too rare.

The Gambling Vending Machine would give out 2 products instead of one 25% of the time, it would dispense 3 5% of the time and according to a bloke from the pub, it’s been known to give out 5 products at once, although reliable witnesses are sketchy. To finance all these freebies, all items cost 50% more than they usually would (e.g. a 40p chocolate bar would cost 60p in a Gambling Vending Machine). This would lead to slightly more profit than a regular vending machine.

This would be treated as an alternative to the regular vending machine rather than a replacement. People would get the choice whether to pay the regular price and get the regular one pack of quavers or to pay the little bit extra for the chance of being in crisp heaven.
