Bench Conduct

[CA BBall Ref]

Tonight during a varsity girls game the visitors bench would begin to cheer in unison, DEFENSE & then clap, clap. At the first dead ball I asked the coach to have them knock it off. She asked for a rule citation and I gave her bench personel are free to rise and spontaneusly cheer a play. I told her her teams cheer was not spontaneous, rule 10-4. My partner and I talked about it and both agreed. They are either players or cheerleaders. How are you handling this situation?
