One day 3 immigrants

One day 3 immigrants were sitting in a bar: A Syrian, an Afghan and a Turkish The Syrian finishes his beer, throws the glass in the air and shoots it with his gun. As pieces of glass are raining on them he says "In Syria glasses were so cheap that we never drank from the same glass twice" Then the Afghan finishes his beer, throws the glass in the air and shoots it with his gun. Again, as the shattered glass is falling he says: "In Afghanistan we had so much sand. We made glasses with the sand, so we never drank from the same glass again". Finally the Turkish guy finishes his beer and throws his glass in the air, before he can say anything the bartender shoots all three of them and says "we have so many immigrants here in Germany that we dont have to serve them twice"
