I am not sure if this is going to come as a surprise little fact about Philadelphia for you midwesterners or not, but Philly-folk love their convenience stores. In particular, they love Wawa. You cannot go half a mile in any direction without having a Wawa at your disposal. I have NEVER gone to a Wawa when it hasn't been busy. People use it for everything. They get sandwiches, fruit cups, shakes, coffee, ANYTHING. I once found gravy in sipable form at a WAWA. I wish I was kidding.
People rank their WAWAs. They have their number one WAWA and a back up if needed. I just don't recall the big love for convenience stores in the midwest. Maybe in Iowa, where the fountain soda flows from about 25 different spouts, but there is as much commitment and love for WAWA as if it were a grocery store. Why don't people just go to the grocery store?
