From the state where drink driving is considered a sport, comes
a true story from the Sunshine Coast, Queensland.
A night patrol police van parked in a dark corner of the car park
at the local hotel. A little latter the officer noticed a man leaving
the front door so intoxicated he could barely walk.
The man stumbled around the car park for a few minutes, with
the officer quietly observing. After what seemed an eternity and
trying his keys on five vehicles, the man managed to find his
car, which he fell into.
He was there for a few minutes as a number of other patrons left
the hotel and drove off. Finally he started the car, switched the
wipers on and off (it was a fine dry night), flicked the indicators
on, then off, tooted the horn and then switched on the lights.
He moved the vehicle forward a few cm, reversed a little and
then remained stationary for a few more minutes as some more
vehicles left. At last he pulled out of the car park and started to
drive slowly down the road.
The police officer, having patiently waited all this time, now
started up the divi. van, put on the flashing lights, promptly
pulled the man over and carried out a breathalyser test. To his
amazement the breathalyser indicated no evidence of the man
having consumed alcohol at all!
Dumbfounded, the officer said Ill have to ask you to
accompany me to the Police station, this breathalyser equipment
must be broken.
I doubt it, said the man, tonight Im the designated decoy......
