Optic
Posted: Sun Dec 14, 2014 11:45 pm
I'm in the middle of a British mystery, and a lot of the action takes place in a pub. The writer keeps saying the bartender fills the tankard or whatever from "the optic." In context the optic appears to be the handle or lever on the spigot that you press or pull to fill the glass. I can find no record of this use in any of the several dictionaries I use. Can anyone help? Is this a British isage?
