When I was a bartender, we were pouring to (what we thought was) just below the rim of the shot glass, I assume because we didn't want to spill.

My boss saw it one night and was pissed. He poured 2 shot glasses like we were, then poured one into the other. It either all fit or only just barely spilled.

Volumes of tapered cylinders can be deceiving.

I love that your manager was pissed that you were underpouring.
