Depends on the level and people Snaqwells-
I was at a freshmen girls tournament where the students running the table constantly hit the horn when the coaches from one team but not the other were attempting to call timeout.It was a three court set up and between whistles and horns from other courts things got quite confusing.Eventually the coaches from our school asked the refs about this and they put a stop to it.
I have also seen a high school student handle a varsity girls game (running both game and shot clocks) and do a very passable job.He did better than some adults I have seen when they only have to run one or the other.The point is kid or adult people in "The Trench" better know what they are doing or you and your partner are going to be in for a long night.
If you have people that are unprepared at game time there really is not a lot you can do about it.Just get in, do your game(s),and get out!Maybe an email to the AD the next day is in order if it is really bad.How many of you have taken this step and did it get you anywhere on the next visit to that school?
