This is a hot tub with people in it, and a bartender (more like hot tub tender) to give drinks and food to the people in the hot tub. On the side is the hot tub heat generator, and on the other side is a trash can so the bartender can throw away empty drink bottles or rotten food. Leading up to the hot tub are the hand rails to grab on to as you position yourself in the tub. On the side of the tub is a button that turns on the heat if you press it once. If you press it twice, the bubbles will start.
