According to the complaint (p 2), if I read it correctly, BC allegedly gave the minors alcoholic beverages at the tennis club, not the mansion.
Here is the complaint so you can read it in full and form your own opinions rather than rely on someone else to read it and try to interpret it for you:

Why don’t you take a look at it and answer your own questions? :-)

Thank you. I will do that.
Does BC have a still located in his rectum or something ?
