My dad works for a winery and they have a dumbwaiter between their tasting room and storage cellar for sending up cases of wine. When I was a little kid I was with him at work one day with a friend of mine. The ladies in the tasting room needed a bottle of wine sent up from below. So my dad let us climb on it and he ran us up to the other floor. The woman opened the door up and there's two little boys holding the bottles she was waiting for.
