"A Full and Complete Stop"

A little while ago, I was on a flight back home from a business trip.
     
After the aircraft landed and was taxiing toward the gate, the head steward got on the PA system and began the oft-repeated speech about destinations, gate locations and the service people waiting to help you.
     
Then, as the plane approached the gate, some passengers looked restless, and it appeared as if they were about to stand up.
     
Seeing this, the steward announced, "We have invested a lot of money to ensure that your flight has been safe and comfortable.  We are also looking for ways to save money, and this aircraft is participating in a new experiment.  To reduce costs, we are asking for volunteers to help clean the cabin upon our arrival.  Those wishing to volunteer for cabin clean-up, please stand up before we come to a full and complete stop."
     
Not a single passenger left his or her seat until we were at the gate, and the seat belt sign was turned off.
