The equivalent rank muppets are out there still - I find them as fun and interesting to deal with as the many retired RAF and other military personnel who continue to use their military rank long after they've left the service and gone into new jobs.
Quite.
I worked with two. One, a Lt Col/C1 aka Bob. The other a Lt Col/C2 aka Colonel ******. The latter had a loud voice too.
As a Sqn Ldr/C2 I never used my rank although I was wearing the uniform, the two colonels were true civilians out of uniform. There was also a real time server a Major/C2 who again was Major.
