While going about their duties, one of the waiters 'trips', and smashes a silver tray (noisily) to the ground. Another waiter rushes to his aid in an attempt to avoid a scene, which in fact creates one. A minor 'tussle' erupts and before you know it, the waiter breaks into a tap dance on his dropped silver tray.
As the evening progresses, other waiters spontaneously erupt into a tap dance performance in a bid to outdo each other. To the surprise and delight of guests, all three waiters eventually join together into a choreographed and cleverly scripted stage performance, complete with backing tracks.
