if you're going to try and communicate with someone in a language you don't speak, with a phonology you are unaware of, the least you can do is not get *angry* at them for not understanding you

This reminds me of the somewhat unrelated incident in a coffeeshop in Hamburg, where the employee behind the counter insisted on negotiating a language we could speak in common, after I had successfully ordered without using language, in order to ask if I wanted anything else.
