Detroit is a Midwestern city, whose main industry is auto manufacturing, so it is hardly surprising that the city is somewhat conservative when it comes to business. Although immensely friendly, its citizens are hardworking and efficient and see to it that the working day is not wasted. Formal business wear is often the norm in the office and certainly always worn for sales calls or when meeting business associates. Working hours are typically Monday to Friday 0900-1700, although some variation or even a slightly longer day is not uncommon.

Entertaining usually takes place in restaurants for lunch and dinner, and home visits are rare. Don't exchange business cards until after dinner, and always address your business partner by their last name until you build up a strong working relationship.
