Re: How do you handle late comers?
Is this cash or tournament? In a cash game, it doesn't matter. He doesn't get his chips until he arrives, and if you offer rebuys, well anyone can reload.
If its tournament, that's different. If he's committed to attending, his stack must be at the table and blinded down until he arrives. Since its a rebuy, I don't see the issue with him rebuying when he arrives at all, so long as all the other players have the same oppurtunity during the same time.
In my weekly/monthly game, I tell every that if you're going to be late, tell me. You will be blinded out till you arrive. If you're not in your seat by the end of the second blind level, I remove your chips and you don't play. I have yet to enforce this as everyone shows up by the end of the second level of play.
