I have worked in pubs in clubs most of life even as a kid I started to collecting and washing glasses in my parents pub.
Even in the 70's landlords were strict who wanted a drink in the pub the fines aren't just worth it. I know some young women chanced their arm and sometimes they got served but it took a lot of effort to make themselves look older in the 80s. However when they got challenged for I.D they soon abusive and walked out.
I can't speak for everyone but I never went back to a stranger's house after a few drinks. How could of JK gotten drinks for an underage lad without being challenged ?
