One I didn't see.
I was at uni, just got out of my car (I went to uni in my 30s) some bloke parking in the street made a comment about my breasts that just made me feel shit, like he was doing the 'I am a man, I have power' routine.
I went in to the building to get my usual coffee and the lovely lady serving could see I was upset, she told me to get his reg number and she called the police.
Very nice policeman turned up and took a statement. He asked me what I wanted to do, did I want to make a complaint and have him arrested, or 'a word' from the police. I opted for the latter.
While I was there he radioed through the reg. It turns out it was a company car, so nice cop set of to chat to his employer, find out who he was and let his employer know what he had done, and how upset I was.
I used to quite often travel on the M6 toll.
If you have not been on it it is much much quieter than the usual M6 and so some people treat it like a race track.
I used to keep my eye peeled for the bottle green VW polo, the kind of car boy racers like to tailgate and intimidate, not realising it was an unmarked police car.
I've seen so many people pulled over.
