Customary dealer knocks on the table before the flop. Why is this happening? Where does the custom?
I've also seen players win/ lose treated the same way, knocks two-three times, What's up with that?
So thats what that means.. I've seen it so much but never put thought into the reason. I always just kind of figured the dealer taps the table to signify the pot is right.
When dealers do it, it signifies that all action on that betting round has been completed - note that they'll do it before they deal the turn and river as well.
When players do it at the end of a hand it's just the equivalent of typing "nh" online.
