Traffic and sex

I have the impression that Spanish policemen tend to be a lot more lenient on women than on men. This happened to me on Friday night.

Policeman  waves about a light to make me stop and carries an alcoholimeter in his hand.

Nia. Good evening again, officer. 

Policeman: Have you been already tested?

Nia: No, I was the copilot on a car that passed by a minute ago. 

Policeman: Right then, go ahead. Good evening.

He didn't test me. A driver in her twenties with loads of smudged make-up on a Friday night at the hour the bars close.
