Free lunch

There is a saying in Economics "There is no such thing as a free lunch." The whole concept is there is always a price to pay for everything, it just may not be money. Well if that's the case then give me as many free lunches as I can if all it costs me is a couple of hours of time at work. Of course, the other cost is how sick I will get from eating Pizza Hut but that's a different story for a different day.
