quick checkup please:
Dealer is ready to put out a flop, and as they are collecting the preflop bets, they bump the stub with their free hand and the top two cards come off the top of the deck and land on the felt face up. The cards bounce around a bit so there's no way to discern which card was supposed to be the burn and which was supposed to be part of the flop, and the dealer readily admits to having no idea which card is which. Dealer then calls the floor over to explain how bad of a dealer they are.
Wat do?
