Perhaps the dudes there should focus on convincing customers to buy their products rather than NOT…read morebuy them. One of them started telling me about this Hamburg ball cap that "it's the Burg", to which I replied that I knew that very well because I had been living in Hamburg for seven and a half years. He didn't even let me finish the sentence, but interrupted and told me that "no one in Ausland would recognize it, because there's no 'Hamburg' written on it". He just assumed that I'm just going to the Ausland with it (maybe because I looked like an Ausländer to him)‍. Really, a good salesman convinces people to buy stuff even when they're inclined not to, rather than dissuade them from buying when they definitely want to.
