Other than coming to the rescue to my sister and her kids in their broken down Mk4 a few years ago, I've not come across any Damsels in distress.
The closest was stopping a woman's car from being stolen.
Pulling into a space at Parc Tawe, Swansea, I noticed the car ,two spaces to the right, a chap bending down under the steering column. After getting out of my car I noticed the chap had vanished and the drivers door wasn't slightly ajar.
So..Hmmm. I waited for about five minutes, thinking they might come back, but then then it became obvious . I had a quick look inside and it seemed ok. Locked the car and went to the security lodge to report a potential theft. This was a Saturday. No-one there! I then spent about 40 minutes walking around all the car parks to find High Viz Noddy. Was he there? No.

So, I left a note on the windscreen about what had happened, and that she should get in touch with security to view CCTV.
I got a very nice phone call from the female owner which showed me that "doing ones bit" should always be encouraged.
Warm and Fuzzy FTW!
