When to leave?

When in a B&M cardroom and you wish to leave, when would be an appropriate time do so. Im talking position wise..Is it ok to pay the BB and SB...see your free hands and leave right before you have to pay your BB again? Or should I pay my blinds, play 3-4 more hands and then leave?

I've never seen someone leave except when they run out of chips or the big blind is their's next.

Does it really matter? Just leave.

It's fine to play your BB then leave after you see your free hands.

I try to leave right before my BB is posted. Sometimes I'll go earlier if Im tired and someone requests a setup, or the dealer changes, or anything else that holds the game up.

Right before they collect time in the 1/2 NL game.
