[EX Q]: Question: What is the current population of the city that Marcus personally delivered a fur coat to a customer in? Passage:As a retailer, Marcus believed strongly in making his store into a place where everything a customer needed could be found and, if necessary, brought to the customer's front door. He was said to have helped one customer discover the shoe size of Queen Elizabeth II so as to give the gift of stockings and a pair of shoes, and he ordered that the store stock such items as a set of Steuben plates with the Mexican national crest, "because sooner or later somebody will be going to call on the President of Mexico and need a proper gift." He personally delivered a fur coat to a St. Louis, Missouri, customer who could not make the trip to Dallas. Another story often recounted is that of a shopper who, in searching for a present for his wife, said that he was not sure what to buy, but that he would know it when he saw it. In response, Marcus inquired about the woman's clothing sizes and asked the customer to wait briefly. Taking an oversized brandy snifter from a display, Marcus gathered cashmere sweaters of various colors, arranged them in imitation of a pousse-café, topped with a white angora sweater to simulate whipped cream, and in place of a cherry, garnished the concoction with a 10-karat ruby ring, at a total cost of $25,350, which the customer gladly paid. When one customer decided his Christmas purchases were not sufficiently impressive, Marcus helped to arrange a full duplication of the store's display window, complete with mannequins and lighting, inside the man's home.
