I LOVED working at the assemblies back in the 1960s! (Yes, we could do that back then - volunteering for the various food services (from meat-cutting to cooking to serving to cleaup) In short order I figured out that the PRIMO - ABSOLUTE BEST - volunteer position was NIGHT WATCHMAN. Why? Because you had to be awake ALL NIGHT, which meant you slept during the assembly sessions.
I lived in New York City, and one year - might have been 1977 - our district or regional assembly was in Washington D. C. in a sports arena that was about six city blocks from the White House. It was summer. It was hot. It was humid. We (night crew) were not given access to the showers in the arena until 3 hot humid days had gone by and all of us profusely sweating young men smelled like excellent cave-aged French cheeses! We were RIPE! Our loving daytime Brothers & Sisters would stare at us when we passed because our aromas were intense! When the assembly elders finally got permission from the arena managers for us to use a shower facilities, I took my "inner garments" and threw them in the garbage!
I avoided most of that assembly, AND I was admired as "spiritual" for being willing to volunteer to advance Kingdom interests! What a laugh!
