Oh sure, that's entirely fair. I think at the time, too, it was far more common to have people yank out their phones to pay than to dip their Apple Watch to the card reader, which was part of it for me - clerks were expecting me to hover my iPhone over it, so that's what I did.
What's funny is the number of times I've had to correct store clerks who would see me pull out my phone and say, "Oh, we don't take Apple Pay" and I had to tell them that if they have a "tap" system for credit cards, they take Apple Pay.
Fortunately, too, they've been grateful for the education.
