In restaurants, tip waiters about 15 percent and as much as 20 percent, if you are more than satisfied with the food and service. The same applies to bartenders, taxi drivers and hairdressers. Tip one US dollar per coat at a coat check, one US dollar a day for chambermaids in upscale hotels and 50 cents per bag for bellhops. Baltimore is relatively conservative as far as dress is concerned and in the more expensive restaurants, men are expected to wear jacket and tie. You might feel conspicuous in public areas such as art museums and theaters if you are not neatly dressed.
Business tends to be conducted in suits, worn by both men and women.
Some of the city's business community takes a more open-minded approach and less formal attire may be acceptable in many situations. A group of small scale entrepreneurs who hire horses and carts to sell fresh produce, they have been vending their way through the streets of Baltimore since the early 1800's, though now, there are only twenty-five arabbers still in business. Nevertheless, they are an example of how zealous this city is about preserving its traditions.
