We talked to a guy last night, in the grocery store, who had served in the Navy, got out and later enlisted in the Air Force, of which he retired from as an E-9. His age, I don't remember, but he did serve in Afghanistan. He is only the second person wife and I have met that had served in two different Services. First one, we met at a hotel in Pigeon Fork, TN. Short hair, so I thought he was either a police officer or fireman, but nope. He had been in either the Army or Marine Corp first, ask for his Honorable Discharge as a Sargent and got it. Started college and got a job. He told me, "it didn't take me very long to see the lack of supervision/discipline in a civilian job, so he quit and enlisted in the other Service. They found out he had some college, he got an officers commission and retired a full-bird Colonel. And, I would tell anyone myself, just how lacking supervision/discipline is in any civilian job, or at least many of them. But, just think, serving in two different military services........wow!
