Was in a club in Camden and this German girl asked me 'hey how do I get a beer?' So I walked with her to the bar to buy her a beer cos I was feeling nice. It was later pointed out to me that she had been flirting with me for about half an hour before this, and it was clearly a last resort to get my attention.
What makes me laugh is that if I responded her question by essentially saying 'Yes! I do know how to get a beer! Come with me to the bar and watch how I totally know how to do that!'
Also, tho depressing at the time, the idea of the 19 year old me knocking door to door, trying to sell double glazing is pretty funny now. I lasted a week.
