I wish you worked with me, in that case.

I've had the pleasure of working with many different people from different backgrounds, including many Brits. I've always found the dry, understated humor from them to be endearing, making casual conversation more interesting. My parents are both from the Middle East, my wife is from Southeast Asia, and I have many Middle Eastern, Desi, African American as well as African (as in continental) friends, so I may not be a "typical" American in that regard.

That being said, don't underestimate the value you bring by sharing your cultural insights. I don't think I told anyone to their face that appreciated their cultural value, but I hoped that my engagement and cheerfulness in dealing with them at least communicated that I was happy with their presence.

It might be that your engagement with someone opens them up to a part of the world they've yet to experience or know much about. Granted, there are lots of places with more gaps than the US and the UK, but there's still value in that and I started with those examples but mentioned it comes from all sides.

Cultural insights are one thing but the issue is if you slip into full flow of Britishisms and let your accent loose people who only speak English as a second language can't understand what you're saying.

There's nothing unique about this though, it's the same for every language - it's one thing knowing Spanish well enough to hold a conversation where the other person is speaking slowly and making it easy for you, it's quite another to be able to slot into a group of native Chilean Spanish speakers in full flow.

I travel a lot so I'm used to adapting my use of English depending on who I'm talking to. I find there's a way to express things and still enjoy using the language without making it hard for non-native speakers to understand. But also, when you do end up in a group of entirely Brits it is fun to be able to just let loose
