After we introduce ourselves, the R usually ask the home coach "what do we have tonight?" The coaches will tell us if they are going back to the locker room or not, if there are events during halftime that will make it longer, etc. The R then asks about legal equipment. Then comes all the "optional" things that the R may or may not tack on based on their own way of doing things:

Are you calling your own timeouts? Do you have a questions about bench decorum or the coaches box? We'll try to talk them out of stuff. Any medical issues we need to know about? We don't care about the coaches box, as long as you are coaching. If you have a question don't yell across the court, we will rotate around. Are you aware of the new POE on hand checks? Let us know on timeouts, we won't start the clock until you are in your huddle. Are your players going to be wearing their uniforms properly, tucked in? Have them out by the 2nd horn. Are you players going to exercise good sportsmanship tonight? We are gonna answer questions, ignore statements, penalize insanity. Be respectful of us, and we will be respectful of you. Etc, etc, etc. Did I miss any??
