The floor was called as some cards had got mixed up during the deal when one player assumed incorrectly that one of the dealt cards was meant for him. Consequently one player in the small blind only had one card. The players assumed that it was a misdeal but the dealer called the floor.
The floor explained that it was not a misdeal. The players who didn’t have legitimate hands were mucked but the valid hands could play out the hand. It wasn’t arguably directly the fault of the player in the small blind but he had to surrender his cards and the chips.
The golden rule is to protect your hand. Even as it is being dealt to you, pay attention and secure your cards and speak up if you see something wrong. Most of the time nothing untoward happens, but it does happen from time to time and it was explained it is the player’s responsibility.
The players accepted the ruling but the debate rumbled on for a while.
