In RVN in 66 you could still buy booze as an E4
I remember 40 oz British quarts of Gilby's gin and Vodka $1 each. Rose's Lime juice $2. Smokes 10 cents a pack, beer 15 cents. Me and my pal Habgood tried to drink a bottle of each one night and after we passed out they blew up two helicopters that night, we didn't come close to waking up. One of these: "Get up this is a red alert!".... "F**k you"..."That's f**ck you SIR!"..... "Oh, be right there SIR" My mouth tasted like the bottom of a bird cage.
