I have used Apple pay with my 6 a dozen or so times successfully. Yesterday I attempted to buy a $7 sandwich from Subway and the transaction failed. I have used Apple pay at this particular location a few times. I would push the Home key and hold it over the reader and Siri would pop up instead of Apple pay. There was no one else in the store except the salesman and me so I kept trying and trying, at least two dozen times with no success. I asked him if he pushed the Apple pay key and he kept saying he did. So was I doing something wrong or was he doing something wrong?
