HS end game events

[so cal lurker]

Do y'all ever give verbal warnings below the the threshold of a formal warning? I'm frankly surprised how much some teams touch the ball after they score,and how rarely it seems to be addressed (from the stands I wouldn't know if there was a mild "knock it off" from the ref)--even when that team is setting up a press and gaining at least a marginal advantage from the contact. (And I have the un-quantifiable impression that it happens more with the referee teams that I would consider less skilled.)
