Free food. It used to make the conventions almost bearable. I rememeber telling the wife and kids to NOT put anything in any contribution box, because as the head of the family, I had taken care of it. LOL. And you would not believe how wasteful I was. I remember one time I got 5 hoggies, and took one bite out of each. And one time I got a bag full of food and took it out to the homeless (aka bums) that were hanging around. Gee, I miss those days.
Now I have graduated to putting nasty notes in the contribution boxes, and taping "the truth" on bathroom stalls.
