Two players playing nine ball for a small wager. Playing rack your own. Player A racks the balls, but inadvertently places the nine ball at the back of the rack. Player B notices this but does not say anything. Player B also shh's the couple of spectators who also noticed the error in the rack. Player A breaks the balls and the nine goes in a pocket. Player B jumps up yelling foul, and grabs the cue off the table. Player A is like what foul. Player B with the help of the spectators states what happen. Bickering starts over if it's a foul or not because you let them be broken. Or is Player B just an a-hole for not pointing out the error in the first place.
