Launches are many things to many people. Some go more to experience the event, watch the flying, and talk to people more than others. Others go more for the active flying, not to talk, but experience talking and seeing other models flying, and so on.
I know when I'm able to make it to a launch, it can vary widely as to what kind of flying I'm planning for the day. If I am testing out new model designs, or practice flying models that need to get flown a lot that day, I won't be doing as much talking. On more laid-back days I'll take a few models to fly, sometimes for the heck of it, and play the launch by ear. A lot more talking, and having plenty of time to help someone out. Does not mean I won't try to help anyone when I am doing some intense flying on a busy day, but less time available for that so I prioritize in those cases (such as someone having trouble say a glider, I'll try to help with that even if I am busy. While someone with a generic rocket problem like installing Estes ignitors, plenty of other fliers can handle that if I am otherwise busy).
The most intense prepping I've done where I did not want to be talking with anyone who was not involved with assisting was in prepping my full stack Space Shuttle that separated the SRB's (6 chutes total), a Flight Computer in the ET (which dual electronic ejection charges, and a total of 4 chutes) and orbiter glided down by R/C. A 1.5 hour complex prep, with detailed checklist. Needed to concentrate on getting everything right and not miss anything. But most of the stuff I fly isn't anywhere near that complex or intensive to prep (that's the only one that justified a checklist).
