When I was a JW - many moons ago, I hung around the 'Sound Department' at Assemblies.
They finally put me to work - and let me do things like string wire for speakers, install speakers, etc.
I eventually learned how to adjust the amplifiers for proper volume, too.
Good experience and training, that I don't use to this day.
Anyway - I also was allowed to adjust the microphones for the 'speaker' who would be giving the next talk.
This usually involved following the feller out to the podium, and raising, or lowering the microphone to the proper height fer picking up the words from the fellers' mouth.
Some required very little adjustment, whilst others required major raising - or lowering.
This one time, I recall going out there, and they had used a NEW microphone stand - one that had a ring, or collar arrangement that you just squeezed, or rotated and lifted, to move the microphone up or down, as opposed to the older type that required one to unscrew a locking collar, and then raise or lower the microphone.
I had not tested this previously - and only seen others work it, but it looked easy enough.
So, I follow this 'big-wig' out there, stand there, grab the upper section of the microphone stand with one hand, and then with the other I am attempting to <grunt> <grunt> get it... to ... release.
It wouldn't budge!!! (It was cause I didn't know the 'secret' on how to get it to release.)
I was there, for what seemed like an eternity, trying to work this thing, then finally reached up and adjusted the horizontal arm - in a vain attempt to adjust the mic (it also refused to cooperate, and I think I only adjusted the microphone a total of 1/8").
The 'big-wig' speaker musta noticed my total and complete embarrassment (I usually turned beet-red in the face), and nodded that it was adjusted properly - so he could git on with his part.
I skeedadled off that stage - and made a mental note to figure out how to adjust that new type of microphone stand - later.
Sheesh!!!
In retrospect - it was funnier than heck. At the time - I was mortified.
