A customer rattles off a drink I've never heard of and I just stare, then reach for the little cheat card I keep hidden by the register. Every order takes me twice as long as it should, and I can feel the bartender next to me picking up my slack. I'm the slow one, and everybody behind the bar knows it.
More people experience this than they realize.
You don't know the drinks yet and you're the slow one behind the bar.
