Issue at Table 48
There was an issue at table #48 that invoked yelling between players and eventually the floor was called. It seems that one player shoved all in and the action was folded around to a player who said "Four?" asking how much it is. The dealer asked the player what he said and once again he said "Four?" asking if the all in was four-thousand more. He pushed out chips and flipped over 
and the all-in player blew up.
The player that was all in insisted that the caller said "Fold" and not "Four." When the floorman came over he attempted to ask the dealer the story but the all in player kept shouting over the top of him. The floorman had to warn the players to be quiet so he could get the story straight from the dealer. Afterwards, everyone at the table said that they also heard "Four" and the hand was played out with the all in called.
The player that was all in flipped up 
and was significantly behind. He did not improve with the board and stormed off toward the rail.
