That actually happens a lot. In my country, an old man of indigenous origin (who by the way get a lot of discrimination here), walked into a Mercedez dealership and asked for the price of a Truck. The salesman made fun of him he assumed the man did not have the purchasing power and treated him like crap. When the other salesman, a good one by the way approached the man and gave him the price. The gentleman took out a piece of cloth with a huge bunch of cash in it. He said I want 2. The funniest part was the first guy actually complained to his boss that the other guy stole his customer. He said that everything he did was part of his "sales approach."
