Fresh New Questions After Webinar Experience

Well, I finished my required ITA Webinar last night (in a mere 123 minutes), and it was quite the experience.  Here is a summary of the moments:

*  Great technique and knowledge of the leader.  He knew his facts and expressed them well and succinctly.
*  Spent way too long listening to endless questioning and rabbit-chasing by an official asking incessant questions.
*  After listening to some of the questions, we now know that more training is needed for some officials.
*  A tad too much time to given to MTO's and bathroom breaks.
*  Overall, I would give them an A- for the webinar.

After I was able to clear my mind and head, I wanted to put this "How Would You Rule" question before you...

SCENARIO

In a men's Division I singles match, player A alerts the chair official that he would like the trainer to come out and treat him on the next changover (perfectly legitimate request) and the chair agrees to do so.

The fans for Player B have already been given an official warning for spectator conduct before the changeover.

As the trainer for Player A comes out onto the court, the fans for Player B began to boo and yell catcalls directly specifically at the trainer.

What would you do?

1.  Do nothing since the trainer is not one of the players involved in the match.

2.  Give a point penalty to Player B for crowd misconduct.

3.  Give a warning to the crowd about abusing the trainer.
