I love it when you are withdrawing a substantial amount of money, and the bank staff ask you "what is it for" ... my reply has always been "drugs ... and make some hookers, but mainly drugs".
Nosey gits.
Last time, I replied "That's my business, it's my money and I'll spend it as I see fit."
About 4 years ago, I was on a night out and walked across the road with my hair blowing everywhere, I was greeted by an absolutely hammered girl wanting cuddles and asking if I was in boyzown(because of my blonde hair presumably)
I thought I'd use it as a cringey attempt at humour here!
