I think at Subway, you are paying to much for the “name”. Years ago when it first opened, I decided to try it and bought a Sub in Brooklyn.
I paid more than I would have at Subsantional, for 1/3 of the meat!
Haven’t been back since!
I do also have an issue with the “Kosher” Non Jewish chains, etc, but not the biggest deal, its the sad reality of our world now.
