Your secondly is the answer to your firstly lol. The tournament is everyday for one. The pool Hall is huge , It is the biggest pool hall in southern California. It hosts all of the counties Apa teams !! The pool hall has its own apa area with banners and lots of tables far from the many many 9 foot tables. What that means is you just can't call time out and run over to your team mates. Because you have huge numbers of players all around you . And at the tournament side you have even more because this place is become insanely popular because it's owned by Efren Reyes child hood friend and Efren has been going their allot. So again you just can't run over their. I will make a video of the place on that night and you will see lol. Like I said the team is not committed to the team. They are more worried about the tourney.
Well, every league will operate a bit differently, I suppose. But the room would have to be shopping mall sized to not be able to take a minute to go grab someone. As I'm just a hick out in the sticks, I may not be aware of such places...

One of the places we play is a bowling alley/sportsbar/entertainment complex. It holds seventeen 9-foot tables, so it's pretty good sized. (They used to play indoor golf in this building.) This doesn't account for the outdoor smoking area at the far end of the building. If I need a coach, and the guy isn't around, I go get him. If it's gonna take more than a minute or two, then I'll blast away on my own.
I would have him ask (or have you ask/suggest for him) that at least one person that is capable of coaching be in the neighborhood while he's playing.
But that's just me. Maybe he needs to be on a different team next session.
Best of luck to him.
