Hungry jacks harvest

The act of going into a hungry jacks store (or drive thru) and ordering food only to surprise the cashier with several iOS and or android devices displaying shake and win vouchers for the items you had ordered (usually through the use of a hacked app or screenshots) to avoid paying for anything.

Guy one: let's do a hungry jacks harvest I have 3 iPhones and an iPad
And they all have hacks to get everything for free

Guy two: yeah let's do this it will be hilarious when they expect us to pay $20 and they find out they have to give it all to us for free LOL
