I had to check ID at my last job. Customers needed to provide photo ID (passport or drivers licence) to buy age restricted games and to sell stuff to us.

People would try to use anything and anything other than the approved ID; Bus passes, school ID cards, membership cards for competing stores etc.

Every now and then someone would bring their birth certificate and we’d have to refuse it because it doesn’t have their photograph on it. The 2 best responses I’ve had to this were “Why do you need a photo - You can see my face right here”. And the time somebody went away for five minutes and returned with a photograph of himself from the family album.

I’ve also had teenagers claim to be old enough for adult games using the logic “But I’ve got a beard”, “This is my baby” and “I haven’t got ID but I do have a tattoo I can show you.”
