I frequently patronize a fruit and vegetable shop owned by a small Turk. He's one of the friendliest and nicest people I know. I consider him a friend. His face lights up each time I enter his shop and not because he knows that his daily turnover will soar.
He knows my likes and dislikes. He refuses to sell me bad quality, even if something is on display. He knows that I demand to know origins of anything I buy and is proud to source the best products. He will often lower the price, if I wince at the cost of some exotic fruit flown in from afar. If I mention dissatisfaction with something that I have previously bought (occasionally an avocado will be over-ripe), he is clearly pained. He does not charge for the next one or throws in one for free. He gives me only the freshest items from the his walk-in refrigerator, and not items available to the general public.
His reputation has spread far and wide. Customers drive long distances, passing other similar shops, to patronize his shop. It has nothing to do with race.
He knows that I am problably the only customer that has bothered to learn the history of his country and mentions current events, which I have spotted in my scan of daily headlines. He's proud to explain some events or pained by others. He's happy to live in Germany and grateful for the opportunity to make a good living, but is proud of his heritage. He pays back by offering good quality and friendly service (a lesson many German shops could learn).
He knows that I explained the significance of Gallipoli to his daughter, before her trip to Australia. She had grown up in Germany and has less connection to the country of her parents. It took an American to explain the unfortunate and enduring connection between Turkey and Australia to a girl that grew up in Germany.
He wants to show me his hometown, Istanbul, and I want to see it. I need a local guide to help me wander the vast Great Bazaar without getting lost, tempted, or ripped off. I also need a guide to show me the architectural magnificence of the Blue Mosque and Hagia Sophia, formerly known as the Cathedral of St. Sophia (the Greeks and the Turks seem to have "issues" lasting several millennium). This has nothing to do with religion; both are testimony to man's creative genius and talent.
Cultural diversity makes my life more interesting. As much as I like Germany, I would not enjoy living in a town peopled by only one race or nationality. After all, variety is life...
