I played in a NAPA league, playing Lagger's Choice, which is eight, nine, and ten ball. Those rules specifically stated that the 2 and the 3 had to be in the back corners for ten ball. It was a pretty friendly league, so we'd say something about it before the break most times. They even had a poster size sign on the wall explaining how to rack for each game.
Our leagues were winner break and loser rack, so in the scenario that the rack wasn't correct, and the non-breaker made that complaint, it was also that person that racked incorrectly. Makes me wonder if that was the deal from the OP.
