Well I am a dealer and so are most of my friends. So our poker games
are usually pretty good but every now and then we get someone who isnt a dealer and is really slow... well compared to how we can spit out cards.
In this instance we usually take the time out to have a nice slow relaxing hand and wait for the mistake you know is gonna happen. But we all take it in our stride.
Most the time if someone new is really bad I will actually spend 15 minutes teaching them how to deal.. makes a big difference every time.
