Just pasting and resetting? The rest of the time, he could be fetching lattes, making snacks, setting up shade, ... the possibilities are endless! The best part is that if you call him a personal assistant or subcontractor, and it would (probably) be legal to pay salary and use it as a business deduction.

Let's try to get back to the topic of getting people to help at matches.
Another problem I have seen at major matches are the tools who only tape to air paste the stage and then don't do squat after they shoot. Psychological warfare works well on those who already have narcissistic tendencies and electronic hearing protection.

What about stage set up and take down? The local matches here rely on volunteer help for that part as well. If you end up on the slow squad you're screwed at the at the end of the match with target take down. That slow squad also tends to have the highest level of mid-match attrition so you end up with about 4 people on the last stage doing everything.
