No!
Yet people do it for CFA, and have done it in the past for Krispy Kreme (mediocre donuts), In-N-Out (mediocre fast food burgers), and probably a bunch of other crappy fast food places I've forgotten about. And I don't think free food was involved in those (or at least it wasn't advertised that you could get free food by being the first 50 or whatever).
