As I've been told, they* tend to be more polite to you if you make an attempt at least, considering it a gesture of respect for the country you're in. They may roll their eyes at how bad an attempt it is, but it's still a credit.

There is a similar phenomenon in Germany, where we may switch to English, not necessarily because we're annoyed at your bad German, but simply because we consider it more efficient or courteous to engage with people in English. Maybe the French have similar reasons.

I've caught myself in that reflex too: I learned English from the start of primary school, consume a lot of English media, speak English with international colleagues and consider myself fairly fluent. If you struggle with German, I'll be quick to offer using a language we're both good at because it makes things easier for you. That's not a lack of appreciation, it's an offer of convenience.

On the other hand, if you wish to practice your German, I'm more than happy to help. I get the impression that many generally are willing to humour you, provided we have the time for it. If you're ordering at a restaurant or asking for directions, odds are we'll switch to English to speed things up. But if I have the time, I'll gladly listen to your German and offer corrections and explanations.

*Possibly just a specific subset of localities or businesses; I can't give a first-hand account nor obviously make a blanket statement about a country of ~68 million people (1.66 times the population of california, for comparison).

I learned French in France. French rudeness is overstated. In Paris, in high-stress situations, yeah, they don't have time to listen to you stumble through a communication that could be completed in a fraction of the time with greater accuracy in English. But outside of Paris, or in more working class neighborhoods, in mom-and-pop shops, you can get all the practice you need. Stay away from Franprix, and go to the corner bodega, and you can strike up a friendly convo.

I also found that French people express appreciation by correcting you. They assume if you're putting in the effort to learn, you want to know when you make a mistake, and how you should improve. Constant correction can be mildly discouraging to me, but once I learned to take it in the spirit it was delivered, my emotions stopped hindering my communications.

Funny, every complaint I read online about the French seems to apply much better to Germany. But I've never heard the same criticism IRL for some reason
