I'm from the Philly area. We invented the Hoagie (original sub) and we do not consume Subway's shitty foodstuffs. To be from this area and do do so is to shame one's self and you must sew a scarlett letter "S" on all of your shirts to communicate that shame to everyone around you.
And there is no need for Subway when you have Wawa.
