Having worked in a similar environment before, I was always uncomfortable with the official and unofficial restrictions placed on what I could carry on my person.
If I was to appear as overly paranoid or eccentric, I would get less than good evaluations until I was judged incompetent and done away with or I would hear those fateful, dreaded words spoken to me, "Loss of confidence", at which time I would have been quietly disappeared/banished to Antartica or to a LORAN-C station at a desert Pacific Island such as French Frigate Shoal.
I am glad that I am now retired, having dodged those bullets for 22 years and 5 months!!!!! Now, I can laugh every month when my retirement check lands into my bank account!!!!
