Sure it is. We all know you can smell McDonald's food out in street in a passing car. And those french fries they sell, stink to high heaven no matter where you are. Such a foul odor.
My in-laws swear you can't smell their pets when you walk in their house. Trust me, I can. I still go to McD's about twice a year, to get a fish sammich during 'Catholic Appreciation Month' in the spring. Not near as good as I remember them, but some traditions ya just gotta honor...
