I think they also have that rule where if three people check behind you before you have acted your hand is dead.
This is what's called "significant action," I used to see it all the time as a dealer, but would just ignore the players checking out of turn unless the situation was about to get dire, then I would call everyone an idiot and still not kill the hand. It's such an easy method of angle-shooting and colluding.
As for dealing the flop before action has finished, the first thing to do is facepalm, then apologise profusely. If you're dealing in the G then I guess you have to follow their ridiculous set of "rules." Scoop up all the community cards dealt thus far, and reshuffle. Dealing natural turn and natural river is terrible, despite that being the rule at Dusk. With turn and river dealt already, you know three cards that the turn or river cannot be, thus giving 6.5% edge to players drawing to those cards.
Banging the table is a good way of getting everyone's attention, and dealing a spread flop so that any player with something to say has the time it takes you to put three cards face down on the felt to do so. If they haven't piped up by then, then you can start to shift the blame anyway.
