I never have been able to drink during the day, especially if the sun is out and hot or the result is a real buttfuck of a headache. It ruins the rest of my day.
In some Army Officers clubs, where I usually would have lunch when in "garrison", they often served wine or beer. I was amused they allowed us to drink at lunch in uniform.
Because strangely, back at work, daytime on-duty drinking was prohibited. I didn't drink at the Club during lunch anyway, I didn't want any of my bosses to see me doing that. Plus after lunch I usually went to the gym, either worked out or did a 2-mile run outdoors (many posts had a wooded course or a track nearby), came back for a swim if there was a pool, took the sauna, and returned to my office.
Officers were granted rather generous lunch breaks, if we said we were taking "PT" (physical training), which I really did. Making drinking at lunch impossible.
In fact, during my Army years I never drank at all Sunday through Thursday, because most weeks I was required to do organized PT 3 times a week at the crack of dawn. If I dared have a martini the night before I'd feel like I had sandbags tied to my legs the next morning as I was running.
Yet oddly, every Friday after "Retreat" (the cannon shot that marks the lowering of the colors), we'd have Officers Call at the Club. And once a month a "Hail & Farewell" to welcome newly arrived Officers, and to say goodbye to those who were leaving for new assignments. Turnovers in the US Army of the '70s, '80s and '90s were very high. Then you could overindulge with command approval.
But just a little. If you got sloppy drunk you could be officially reprimanded. In fact, I saw one male Lt. Colonel become offensive, with some insults to women, and on Monday he was relieved, and promptly submitted his resignation papers. So your career was always on the line.
Yet again oddly, we also would have a formal "Dining In" for Officers only, in full dress uniform, even spouses couldn't attend. The only enlisted soldier permitted was the senior Officer's Command Sergeant Major (E-9).
There were all kinds of crazy rules of the mess, for which you could be "fined" for violating. Fines would consist of performing some silly stunt, almost like a TV game show. You might have to sing a song, or do anything crazy imaginable. If our soldiers could have seen their Officers being so childish & stupid I'm sure they would have all deserted.
And we all got shit-faced. You could mock and ridicule anyone you wanted, even the General, if one was there. Well, so long as it was laughable. You still had to watch your step, you had to know the bounds at all times, always like walking a tightrope. It was a weird, formalized way of letting off steam, from our normally highly regimented lives.
