Always join an already seated party in a restaraunt, act as if you're meant to be there by saying things like "oh, Susan said it would be fine if I took her place, do you know John? " most of the time they should be too confused to ask you to leave.

"Woke up yesterday morning Woke up today as well And I wake up tomorrow morning It'll make three days in a row!"
