Yes, once in the Army Reserves. I was in summer camp. I felt ill the whole way driving there, and by the time I got there I could barely wallk, let alone report for duty. I went to the emergency room 3 times. The second time was by ambulance. The doctors in their great wisdom, knew I was gold bricking and kept sending me away. Finally my commanding officer spoke up on my behalf and then they discovered I was dying. I musta’ been really good at faking it!
Anyway they were going to operate to remove a diseased gall bladder until my observant mother pointed out that I was extremely yellow and that my liver was not working properly. The drama went on and on, with one incompetency outclassing the last one. I survived, but it wasn’t the Army’s fault, or the doctors attending me.
The ambulance people did their job, and they were the only folks who didn’t appear to be incompetent in that mess.
