True Confession time! When I was a first-year university stdnuet living in residence, I drank Fresca because it was the bottom canned drink in the pop machine in our building. That meant it was the only one within reach when I stuck my hand up the chute and so it was easy to steal it. Hey, I was a penniless stdnuet! Sort of a university Jean Valjean really. The worst part of it was that I hated Fresca, but thieves can't be choosy, eh?Of course, all pop machines now have those theft-prevention shields so this could not be done today. Bastards.
