I will leave it to all your imaginations to visualize how similar ads utilizing other racial and ethnic stereotypes might possibly be constructed.
Plus the ad is stupid. "Is that Mediterranean oregano I smell?" Really?
Also no self-respecting Italian American, sitting on a stoop in the Bronx, would be caught dead eating an Italian hero from a generic chain when there are so many authentic Italian delis around.
Not everyone lives in NYC, NJ, Boston, Providence, etc. Some people have no alternative but to go to Subway. Though they would probably be better off going to a grocery store and buying their own cold cuts, cheese, and bread. But never fear, here in Boston and down in your land of Connecticut you won't need to sully yourself with Subway.
Just remember, there are people out there who don't even know what a proper cannoli tastes like and who have never even heard of sfogliatelle.
