Gin and Bit-o-lemon

Nomis favorite drink (Besides Absinthe) is gin and bitter lemon. I ordered it at the bar and was asked "just a bit-o-lemon?"... "yeah bitter lemon" I said. The barmaid produced a gin with a slice of lemon. So I asked "where's the bitter lemon?" so she said "there" and pointed... I explained it was a mixer I wanted not a "bit-o-lemon", she'd never heard of it, so I said "it's the greeny one"... "Oh that's what it is" she said... so I ended up with a gin and bitter lemon with a bit-o-lemon :-)
