Not so much having to be ID'd but the fact that if I am with my partner and don't have my wallet (I'm over 25 and also obviously pregnant) that he is not able to purchase alcohol for himself unless I hide or pretend not to be with him.
I don't always carry my ID with me, especially if we are just popping to our local supermarket for something for dinner and he is paying but it is so frustrating that I then have to wait outside the door in the cold like a naughty 16yr old so that he can buy himself a beer or bottle of wine.
Does this rule apply to parents buying alcohol if they are accompanied by children who are under 18? Or is it just when it is two adults trying to legally buy alcohol that a problem arises?
