Immediately buying back in for the minimum after leaving a limit game

[Bay]

There is a person who always does this at 30 60 stud8, sits down with 300 then if he wins a pot gets up and sits down again.

short buyins make decisions much much easier. and games like stud8 where there is a danger of being traped it is a greater advantage

IMO min buy in for any game should be 10 bb, and you should have to sit back down with what you stood up with for at least 30 min

There is nothing worse then having someone beat you out of a pot then get up and sit back down with the min buyin
