The only time I'm confused is when there's an unusual card reader, usually a low-budget all-in-one type with a touchscreen, as it's not always clear where the NFC reader is. This is maybe 1-2% of transactions.
Every so often a machine makes the "dur dur" noise and I have to use the chip and my PIN. I'm not sure if this is every Nth transaction, or after spending ¤X. Either way, it's to avoid a lot of contactless payments being made if the card is stolen. (And maybe this is irrelevant in the USA, without PINs?)
"8 out of 10 card payments now contactless in the Nordics" [2]. 54% in the whole EU [3], only 34% in the USA [4].

I as a frequent shopper just like the way I can scan my code at any point and then push one button to check out, and that they allow credit cards to back it. For a while before its launch I think it was rumored that Walmart Pay would require an ACH or debit, which would have made it a hard no for me.
I still think that we've seen major progress. For instance, the huge Kroger chain got on board sometime in the past 2 years after being NFC or Apple Pay laggards. CVS a couple years before that, I remember them being particularly prickly about never taking Apple Pay and they came around.
Lowe's and Home Depot? Walmart, still?
Companies still hoping to silo people into their own apps or antiquated payment method, which might give them a slight cc processing fee reduction that boosts their margins... at the cost of being a usability nightmare for anyone who doesn't shop there frequently. I expect that frequent shoppers will live with whatever a store does, and set up a custom app, if any, or accept using a physical card.
It's easy to see that their approach is petty, because Costco, which has fanatical customers and is members-only—there are no casual infrequent shoppers—got on board with nfc (card and smartphone) payments years ago. If any business could've gotten away with having their own app and special payment processing deals to save money, it's Costco.
