> Oddly only the French did understand the sentiment

French culture is a rare culture where shop owners won't be afraid to tell off/talk back at customers that don't show a basic level of politeness. You, as a customer, are in the shopkeeper's "home", so to speak, and you should behave accordingly. Someone who doesn't use the customary "bonjour/merci/au revoir" is likely to be met with some response like "tout d'abord, bonjour" ("first of all, hello"), or "et la politesse, alors?" ("what about politeness?").

(of course, people from older generations would be likely to say that these things are going away)

I'm French/American, raised across both countries, and even as a kid it shocked me that a customer in the US could get away with "I'll have a coke" as their only utterance to a waiter - no hello, please, thank you.

I suspect this is why the French have a reputation for rudeness. It's easy to understand why tourists from cultures where "the customer is king" would be shocked when they get told off for being loud/rude/inconsiderate.

(I've lived in Japan for a few years now, and ironically enough, I find Japanese customer service culture to be closer to that of the US than France - the customer is king, and while thankfully not too common, some Japanese customers will definitely abuse that dynamic. There's been a growing awareness and pushback on カスハラ, but it's a real thing, and is very cringe to witness)
