I'm 21 and have been IDed for a 15 film recently. I am always IDed for alcohol (age here is 18 for that). People normally say I look 18-19, but people in shops like to make themselves feel like they are justified in asking for ID by saying I look about 14. I don't mind giving over ID, it's just the comments and looks they give with it. I hate the 'oh you'll be grateful of it when you're 40' line. That's stupid.
