This "what places take Apple Pay" thread seems crazy to me being from the UK. Although I guess the subtleties may lie in the spending limits that apply. Do you not have contactless bank cards as standard and general contactless limits for them in the US?
In the UK if anywhere has a card reader it'll 99.99% likely to take NFC (I haven't seen a non-NFC one for a few years now). Everyone uses contactless with their bank cards for lower value payments, which used to have a £20 or £30 limit, but is often now £80 or £100 since covid. If it takes NFC it'll pretty much be guaranteed to take Apple and Google pay up to this base-level contactless limit because everyone uses their phone to pay for everything because it's 2022!
The only limitation is whether the place has a standard >£30 or >£80 contactless limit and so you can't use Apple Pay if above that limit as you have to require card insertion+PIN if greater than that. But some don't and take the full card limit due to the biometrics (or PIN/removal sensing of the watch).
So I guess the point here is that maybe an actual minority of places take *full* Apple pay. But I can do things like my weekly shop using it (big brand store usually = full Apple Pay) and everywhere else from every bar in town that isn't cash-only (which is pretty much all of them) to bus/train tickets to London Underground, to small market stalls and anything general, I'm probably under £40 or £80 anyway, so still works. Some small businesses don't take cash these days because it's a security liability from a burglary perspective and a PITA to take money back and forth to banks/have a till float etc. This then had covid and not wanting to touch stuff unneccesarily too making it the defacto way to pay. So a lot of them do have full Apple Pay higher spend limits than they used to.
If I'm going shopping I'm likely to have my wallet anyway, but I can happily go out to a gig or few drinks with friends and never need to use my card. Thinking about it the little craft beer bar near me we usually get a tab and with enough nice fancy beer we can get that tab easily up to maybe £70+ and watch or phone always works and I've never even thought about it and what the limit is or isn't. It's almost annoying if I have to get my wallet out for some kinda loyalty card scan/swipe since I seldom ever do to pay! (which reminds me I need to go to the app store as I think co-op have a new app so I can use my co-op card out the wallet of my apple watch like the Tesco one now)
I just got back from Glastonbury Festival in England with 250,000+ people in the middle of the countryside on a dairy farm. Apart from a couple of bars which were cash only due to having no card readers and cellular signal to run them off, absolutely every single other bar and shop on the whole site took ApplePay and Google Pay at least up to a limit of more than any round of drinks I bought! And that's on a farm in the middle of the countryside (although admittedly with a lot of extra temporary 4G/3G base stations to give enough cellular coverage for everyone)!
