This is NOT a random store where you walk in

It's DF, you can't get anymore random than that. Those people are not OP's friends.

this is when you're working on some project and suddenly two people in your group start talking in some language nobody understands while you're trying to finish your project. I don't know, but I'm pretty damn sure most people wouldn't appreciate that.

Why? do you get offended too when your friends want to have a private conversation that doesn't include you? Have you even ever had experience working with people who speaks other languages? what you claim "most people wouldn't appreciate" happens about once every two minutes where I work.

Also if "english pls" is already dictating how people are supposed to play holy crap what is this community coming too. Soon you'll need to write a 10 page essay in the most polite writing possible to check whether it's ok to even ask something.

context matters.
