Where did the saying on the house originate from?

Answer 1

The saying "on the house" originates from the hospitality industry, particularly in bars and restaurants. It signifies that the establishment will cover the cost of a drink or meal, often as a gesture of goodwill or to entice customers. This practice dates back to the early days of taverns and inns, where offering complimentary items helped build customer loyalty and enhance the dining experience. Over time, the phrase has become a common expression beyond the hospitality context, indicating a gift or complimentary service.
