I just upgraded recently to the 7 Plus and fell in love with the idea of Apple Pay, assuming that even in my small-ish town there would be plenty of places to use it. Unfortunately, while I'm still in love with the concept, the sentence above (and the joke about the 4 stores that accept AP) is representative of my Apple Pay experience.
I actually went out of my way to stop at a McD's for coffee, bypassing a few other options, only to be told by the girl at the window that they don't take Apple Pay. There are only a couple other places around here that accept it, including Panera, which I don't frequent but I suppose I can try it and see if there's anything there I like.
As it is, I have yet to have an opportunity to use it. I really want to streamline what I have to carry with me, and I'd like to eliminate credit cards and cash entirely. Apple Pay, in theory, could make that possible. So disappointing that so few major retailers in my area accept it.
