I use it at our local movie theaters (Cinemark, mostly). I reach into my pants pocket, double tap with my thumb as I pull out my iPhone, and bring it up to the terminal, which makes a most satisfying bing. And Kohl's now that I put my wife's card on my phone.
Even though Subway is supposed to work, the readers at our local Subways don't like my iPhone 6. I'm waiting for CVS to pick it up, but Walgreens in Sedona worked. Also, our local Ace just updated their readers so it's supposed to work there. Best Buy works, as does Staples.
Hmmm, Target takes Apple Pay online, but not in their stores. Odd.
