LOL, Dawn. Last night, I passed a combination Subway and Papa John pizza fast food place on 8th Avenue and 47th St. in Manhattan. (You can see photos of this restaurant and the building it is in if you search for online reviews of the New York Inn. It gets terrible reviews.)
With both a pizza franchise and a sandwich franchise, I wanted to see what it smelled like. It had the smell of the bread baking in a Subway! It is now clear to me there is a flavoring agent supplied from an external source. The only other baked item I can think of that does this is garlic bagels, made with commercially prepared rather then fresh garlic.
So, this is an interesting discussion. Some people love the smell. Others, like me, are ambivalent. Others still hate the smell.
ADDENDUM: About this flavoring agent, I don't think it is coming from an Air Wick-type contraption. I think it is being directly applied to the bread, either mixed in with the dough or sprayed on the exterior surface of the dough.
