I agree with this, but it would be nice to hear some opinions on how fraud could be limited as well. Reason being that I like this idea and would love to see other people's take on it.

I used to manage a pizza shop and we would run into issues from time to time where we would have extra food. Occassionally it was due to fake orders, but more often it was due to mix ups in the prep area where our cooks would forget to take down a ticket after putting a pie in the oven and the next cook would make it again. If we didn't eat it ourselves, we would call up the local bars, fire stations, police stations, repeat customers or anyone who had a large order in the past and offer it to them at a substantial discount or free. We generated a lot of repeat business that way. We were a small, horribly unorganized shop, so I don't how much that would spill over into the average food business - but it does happen.
