This. There is nothing more frustrating than having a cart load of groceries and not being able to pay as their in-store wifi sucks and there is zero cell signal. I have had to tell the person working at self checkout, "watch my stuff, I have to go outside for a second to load your ass backwards qr code" I now don't shop at Walmart, and i am about to ditch Fry's and go to Safeway for the same reason. Good job losing customers. Thank you Safeway and Target for accepting Apple Pay. I also would be willing to bet, the customers that want/use Apple Pay are people that spend more $ on average. So good job losing us all. Ugh.
