Back in my gin days, it was Beefeaters ----- and the potent stuff, unlike the weak stuff sold in the UK or the newer watered down US variety.
If Beefeaters wasn't avail, I would would pass on gin and give my liver something else to be concerned about ie: tequila, vodka, sake, absinthe, rum, ouzo, etc.
I have alot of stories about Ouzo drinking with the flight/detachment crew in Chania, Souda Bay, Crete.
Theo's El Mundo joint to be precise.
Just did a search of the place online and not surprised the prominent COD plaque (arrowed in pic below) was hanging on the wall. And damn if I remember how many signed US bills I've hung in that place.
Oh, apparently it was a popular place for Einstein to frequent as well :)
