Service is the keynote of any hotel. Today the hungry hotel guest may have a snack in a small coffee shop or a dinner of many courses in a large dining room. Or, if he prefers to stay in his room, he may telephone for room service and order food to be brought up to his room. The traveler who arrives with his clothes wrinkled may call for service and have his clothes picked up, pressed, and returned. Businessmen may call for a hotel stenographer to type their letter. People who become ill may call for the hotel doctor. In addition, many kinds of shops and stores are located in hotels to meet the needs of people who are away from home.
