Actually not quite true.....i was parked up at the time!
A white plain ford focus blocked me in. 4 of those civvy type police (blue bands on their uniforms) got out and one came over.
He said did i mind if i waited until a patrol turned up, they wanted to asked me something......so none the wiser what they wanted I said I didnt mind.
Patrol car turned up and a lady officer explained someone had reported me for drink driving......and they had to follow this up and therefore required to do a breathalizer test.....so i said no probs.
Sat in the back of the patrol car.....while the officer messed about trying to find her breathalizer kit.....only to admit she couldnt find it

and another patrol car was on its way.
5 mins later that turned up......and breath test done....it showed 0
as you would expect i hope.....certainly i knew it would show 0 .
So now you have 4 civvy officers and a car, 1 lady officer in a patrol and a motorway patrol with 2 more men officiers in it........just to give me a breath test

Dont know who gave the report of me suposedly drink driving........and doubt i ever will.....but i am a bit suspucious of how they knew where to find me........may have been chance i guess.
But i will phoning my office on monday (and not the management either......wont get any info out of them....someone else in the company

) and ask if the police contacted them and they gave my gps fix to the police.......would that not be breach of data protection....without proper paperwork request.. :-/
