Well it depends on how you’re going to test it. Are you just making an observation, or are you taking a cotton swab and taking samples and actually testing it? Because scientifically, I would suggest the “real way” with the petri dishes.

Anyways, I would suggest you test wendys, mcdonals, burgerking, KFC, Arbys, Del Taco, Quizno’s, Jack-in-the-box, In-and-out etc. Do as many fast food restaurants as possible.
