When your dealing with $, no matter what game, it's normal behavior for players$ to ''lemonade''.
It's Common, for the best players in an area, to hold their own events at their room, which happens quite often.
Local events are usually put together/run/managed/ to give their best players a leg up on opponents.
Here's a perfect example of what just happened to me this month.
I won the hill and now waiting.
When I got to the event, I arrived 1/2 hr before play started, to make sure how many players signed up/paid.
The numbers were good, and was told it would only be a one day event.

My Next concern before I paid my entry was the cue balls.
I've been to this room a few times and there were many different cue balls.
When your on a 9' it's a concern, moreso than 7'.
Well the TD responded here's what he said.
''I got all tables playing with the same cue balls" he knew it Was a concern, I then registered.
The same person who told me about the cue balls, ironically was my opponent in the finals.
What did he do.
He picked his table also, changed the cue ball, which I commented on ''before play started''.
He laughed/smiled.... it's how this town rolls, always has and always will.
With my background, I call it ''Cheating''.
