Official's mistakes

[gostars]

I was running the clock for my younger brother’s game tonight. The officials were first year officials from our chapter. (I am also a first year official.) They did some things that there was no doubt in my mined were wrong. For the AP throw-in to start the 2nd, 3rd, and forth quarters they threw the ball in wherever the previous quarter had ended not opposite table. There were some other procedural things like not getting the coaches to sign the book or indicate starters. I did not want to seem like I was in charge and not them, but It really bugs me when people don't know what they are doing. I didn't say anything because don't want to seem like a know-it-all. In the past, I have had veteran official not sure how many time outs a team gets. Since they said they weren’t sure when the scorers ask, and I was positive, I helped them out. How would you handle this?
