lol your too young to be smoking you dip shit!!! jk

Ask some elder politely like, "I'm too young and the guy won't serve me...please could you do me a favour and get me a light? You would be doing my parents a favour as it's for my mom" . lol

something like that, I'm not your dad and would never bark orders but if your finding it hard to buy a lighter legit, you shouldn't be toking imo.
