i think the hardest thing for me is not knowing where apple pay is accepted. there's no emblems or markings in stores, and it seems like you have to have a list of places memorized and then awkwardly ask the retail person if they accept it. only place i'm confident going in is the apple store itself. i like the technology and would like to use it more often, there's just no awareness in the real world or how/where to use it. the few times i've tried at places that have it, the people behind the counter are usually confused and don't know what's going on.
