I "enjoyed" those positions about as much as one would enjoy a root canal. Magazine duty was a crock of s***. I always hoped for misdeliveries of magazines that would result in not being able to hand them out, or for the magazines to run out about 2 minutes in. The school assistant position was a little better--I tended to be rather strict with timing, if only to keep the meeting from running late. However, I usually stalled when it came to writing up those slips and handing them out. For sure, it was not worth it--they had better be thankful I surrendered that position before going inactive since I would have shredded every single one of those cards.
The Grand Boasting Session assignments were a true burden. Cleaning meant staying an hour or more late, always with just other men. I remember guarding a donation box at a Grand Boasting Session--the only good thing is that there were probably no sisters using that box (which meant there was that much less going into that box, but I am sure they used the other boxes, precluding creating a deficit of that amount). Handing out the new releases also sucked: at least I didn't have to listen to that discourse since I would be busy handing out the books and brochures. And once I had the job of cleaning the fruits for the a$$embly: I did my best to run out of the damn things long before the program started, creating problems for those who were counting on me to be stuck there until it started.
I think I would rather have the job of drumming up the need for S-77 forms. At least that way I could have a share in shrinking the whole congregation, hopefully faster than they get baptized. After all, it takes six months to qualify for baptism but only two seconds for a S-77 form.
