I can recall as a kid in the late 70s/early 80s, my parents threw a lot of those 60s/70s style "Cocktail Parties." Which is not something you see very often these days among my own age/peer group, even though we're the same age or older as my parents were at the time. Like many other things, I think we're getting less formal as time goes on and the "Cocktail Party" has morphed into more of a gathering or get-together or hangout. Occasionally though I intentionally throw a real Cocktail Party just for the vintage throw-back fun of it.
Anyway, the heart of these Cocktail Parties was the converted-garage "playroom" which actually was more like a game room or an adult parlor with a full wet bar, pool table, mood lighting, etc. And I can vividly recall as a kid, one of the more distinct drinks that one of my dad's friends always ordered, was a "Beefeater's With Four Olives." I had no idea what that was or what that meant, but that was his thing, that was his signature drink, and it's the only thing I ever saw him drink over the years.
