Bizzare experience at supermarket

[pundit]

Yesterday I called into my local supermarket while enroute to a friends place.
As I pulled into the carpark a 20+ year old Fairlane 'bling mobile' was stopped in front of me.
There was a teenage girl standing on the passenger side talking to the driver.
I assumed she had just got out of the car and was about to head into the market.

Anyway she looked at me then looked away and continued talking.
I waited (about 10 seconds)
She looked at me again and I raised my eyebrows and shrugged my shoulders in a kind of "Well are we ready to move now?" gesture.
She looked away again and continued talking.
Then another car turned into the carpark and was appraoching me from the rear.
So time to end this social intercourse. I gave a short toot of the horn.
Well the girl gives me a dirty look and after a few more seconds walks off.
The car moves away and disppears toward the rear of the supermarket.

Anyway I get out of the car and go inside.
Five minutes later I'm back at my car and drive off.
As I turn out onto the road I see the same Fairlane appear from the next exit up and you guessed it,
he's right behind me. So I think maybe this is just a coincidence.
Very slightly I begin to increase my speed and so does he.
About 2kms down the road I decide to see whether he is really tailing me or I'm just getting paranoid.
So I indicate to turn left at a 'T' junction and so does he, then at the last second I don't turn but continue straight on.
Guess what? He too changes his mind too and begins to speed up.
So I decided it was time to just leave him behind. Which I did and about another KM up the I turned off into my friends street.
Well he had obviously stepped on the gas because he went sailing past the turnoff at high speed not realising I had turned.

The Fairlane was pimped out and he was young (Probationary) will the mandatory baseball cap (worn backwards of course)
I figured he must have had a hissy fit because I dared to interrupt his carpark discussion.

Go figure?
