I'm writing in English because first, I can and second that guy is Brit, in other words a British person. And someone who does not speak German very well. So in order to get a proper transfer of information I prefer the language that works best in this case.
If you don't understand, hell I don't care. Get a translator and a crappy translation as a result.
