My friend asked me to work a shift for a birthday party and I said yes without asking what the bar looked like.
It was a folding table in a garage with a cooler, four bottles, and a blender that had seen things. About forty people, no plan, and a cake with a number of candles on it that seemed to be a dare.
I decided, standing there, that I was making one drink and nothing else. I have made exactly one drink well, and a menu is just a list of things you are bad at.
