Set up a scene in which two people are lounging around and obviously gossiping about a third person – who is visibly working at building a tower out of bricks (e.g. large Jenga™ bricks or cardboard boxes). A fourth person arrives, taking food to the worker. One of the lounging pair says loudly, ‘I want some food’ to the food bearer. The worker stops and takes the food, says a big ‘thank you’, then turns to the idle ones and says, ‘Are you willing to work for it? If not, why do you expect free food? You must get your priorities right.’
