Coming soon to a club near you: My driver's license

This is really weird.

I just found out that my driver's license is being used as an example of acceptable proof of ID on a poster at a club at Arlie Beech, Australia, and I'm assuming other clubs too. My friend who went there recently has just sent me a photo of it - shows my current address, date of birth - and of course, my face!

How on earth did they get hold of it? I don't remember ever having it stolen...

Weird.

[EDIT]

Idiot that I was, when, about 6 years ago I added a page to my website about my epilepsy, I chose to includ a small photo of my licence. Just checked it against the one on the poster at the Australian club - it's identical.

Needless to say, I've now updated the page in question! Let that be a lesson to me!
