Hier eine Erklärung zu "front of house" und "heart of house": Hospitality positions are often broken into two types: front-of-the-house and heart-of-the-house. Front-of-the-house positions are those that deal directly with our guests, members, and residents. Heart-of-the-house positions refer to positions behind the scenes, often called the “heart” of the operation. They interact with our guests, members and residents less frequently but are a crucial part of the business to ensure everything operates effectively.
