Local - Grays Inn when I was 16,got a good 2 years in there then my dad took me for a pint in my 18th and proceeded to tell all the bar staff it was my 18th,thought he might've clicked when I walked in and they had my pint half poured.
City centre - The Grill,again 16,first works night out when I tried to keep up with the big boys,threw up all over my mums carpet,hoovered it up and my sister came home later with her pals and quizzes in the morning why the carpet was wet.
Foreign pint - Some hotel in Maastricht when I was 16,teachers bought us them watching the Scotland v Morocco sham in 98 on the annual school trip,all the younger ones got out to their rooms for quiet time and we had a few with them on the promise we told no one as they weren't meant to be drinking either
