How's that Mate?

Only an Aussie could pull this one off ! A true story from Mount Isa
in Queensland ..
Recently a routine Police patrol car parked outside a local
neighborhood pub late in the evening. The officer noticed a man (Luke
Sandery) leaving the bar so intoxicated that 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 bar and drove off. Finally he started the car, switched the
wipers on and off (it was a fine dry night). Then flicked the
indicators on, then off, tooted the horn and then switched on the
lights.
He moved the vehicle forward a few metres, 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 patrol car, put on the flashing lights, pulled the
man over and carried out a breathalyser test.
To his amazement the breathalyser indicated no evidence of the man's
intoxication.
The Police officer said "I'll have to ask you to accompany me to the
Police station - this breathalyser equipment must be broken."
"I doubt it," said the man, "tonight I'm the designated decoy"..
