Delta Airlines introduced a special half-fare rate for wives accompanying their husbands on business trips.

Anticipating some valuable testimonials, the publicity department of the airline sent out letters to all the wives of businessmen who used the special rates, asking how they enjoyed their trip.

The results were mixed. On the positive side, 96% of the surveys were returned — by far the highest in the history of such surveys.

On the negative side, virtually all of the returned surveys contained only one short sentence: “What fucking trip???”
