It is obviously an angle shoot since the guy had A-A. I hope the floorperson that made that call realized that he and the angleshooter are both douchebags after the Aces were flipped up.

A Technicality for sure, but in the "spirit" of the game, the guy did not bet all his chips. This is really the dealers fault for not taking control of the table earlier and warned. stern (usually a-hole) dealers are the best in my book. The nice guys that want peace actually cause the most trouble like this.
