Sleepy
I had to cry whenever I was in UK as they did serve tiny 1/8th of gill portions of vodka, when I asked for a quadruple they did look at me as a nut case and even asked "sir, do you know the meaning of that word?. I replied "yes, fourfold" and had my large vodka.
Our measure is 4 cl and your 1/8th gill is about 1,8 cl. Here beer is served in pubs mainly by 50 cl and your pint is exactly 56,82615 cl. So I was worse off there.
