From 2004 to 2011 I lived across the street from a WaWa. It was great at first, but after awhile it was a real nightmare trying to get to a gas pump. You generally had to wait for someone to leave and then try to beat someone else to the pump. I'm pretty happy with the Marathon station on 466A, the air is also free and always works.
Inside the WaWa, it was nice, but no different than any other large convenience store except for the subs. I usually bought the subs that were ready made in the little plastic boxes that sat in the cooler display in the middle of the store. Once in a while I would place an order and had one made. The touch-screen order system had you decide on everything from type of bread to mayo or mustard, bacon, cheese, I don't think no two sandwiches came out alike.
They added a second WaWa in my town, here's a photo of two cars getting together at the pumps in Bel Air, Maryland.
This is one of the screens for ordering, there is more, it's almost like a test.
Don't get me wrong, I love WaWa Subs, especially if my only other choice was a Subway Sub, those are terrible. However, my favorite is Jersey Mike's Subs. Last week I was at their shop in front of Target and I asked the manager if they were expanding in the local area. He said they are considering putting a store in front of Walmart by NYPD Pizza. That's only a 1/2 mile from the new WaWa location. If that happens, I know where I'll be eating.
