as a kid that used to happen to me when I tried to use my debit card. I didnt try to do it on purpose. If I had known I wouldnt have shopped there. I had no choice and left angry. Many customers arent keeping track of every vendor that does or doesnt have Apple Pay and this will happen on occasion. They know its coming they need to start preparing now. Apple and the banks need to hire a team of execs to handle tarining and installation of these new systems.
