I had an ID that was supplied by some company that came to my school and took a picture of everyone in my year to distribute said IDs.
I didn't have a provisional driving license at the time so this ID was all I had going for me. A few days after my 18th birthday ( which is on 8th March 2007) I walk into the local shop, pick up a few bottles of booze like I own them, and walk to the counter to pay, brandishing this ID.
Guy checks it, points to the "18 on" date. 8th May 2007. I didn't notice this before, but I point out that the "D.O.B" is 8th march 1989, and the "16 on" date is also 8th March 2005. He still doesn't accept it. Fucking great, I thought. I had to wait two more months before I could pick up my own alcohol from this shop, which was a mild inconvenience since it was the closest shop to my house.
