Another thing that I wish I didn't now know.

Fruit flies like brandy, and can fly through the open part of a speed pourer.

Now I get why a) most places I've worked have a "take the speed-pourers out and re-cap the bottles at the end of the night" policy, and b) the few that didn't have those speed pourers with the mesh on the end.

Fortunately, it was a bottle of the CHEAP kind of brandy that you only use for mixing.
