I was in Security Air Police) in the AF as well and served in the UK in the very early 60s.
We had from time to time troops from other branches transition thru our base. The funniest thing was watching these guys stunned look of disbelief when they went through the chow line and instead of having the chow heaped on their plate realized they had a choice of food and also it was served by civilian women. On our base all KP was handled by civilians.
The transients couldn’t believe how easy we had it compared to them and were further astonished we all carried our class A passes with us instead of having to make a trip to HQ to pick them up before leaving base and turn them in when returning.
AF is easier except for Security when pulling fence line or aircraft security in all kinds of weather for an 8 HR shift.
I remember going to the Air Force base in Tan Son Nhut. As an Army guy we were use to plastic eating utensils when we were lucky and just awful food and cold water for showers. The AF guys used real live silverware, had hot showers and slept two to a room. We were invited to eat in their chow hall. Almost killed myself with the metal fork. Wasn’t use to using anything that long any longer. Stuck it half way down my throat.
