an urban legend?   (random re me)

on a similar topic (to the previous post), i was looking for a source to back up the claim i've heard more than one intelligent person repeat, that "taco bell only makes money on their soda sales, they actually lose money on their food" but i couldn't even find a disreputable source! snopes doesn't seem to be familiar with that one, and i don't have the patience to look through sec filings or anything, so i will pose the question and hopefully someone else in the world knows of a (dodgy) source. for the record, i think that claim is a bunch of crap, but that's just my, you know, brain talking. mmm, tacos.
