Here are some ideas:

1. Dealing with slow play
* Bring a small binocular and bird watch.
* Bring some topics to start up to your group. Afterall, it's supposed to be a social game.
* Bring a cell phone. Call a friend during slow periods of waiting. Keep it on vibrate so incomming calls don't disrupt.
* Practice bouncing a ball on your sandwedge. Strengthens the hands, increases eye-hand, and kills some time. Your partners will probably call you "Tiger".

2. Unreliable Partner:
* Lie about your start time to them. Move it 30 minutes ahead of when you actually tee of.
* Offer to pick them up.

3. General competition:
* Keeping score has it's drawbacks, so change the way you make your scores. Don't write numbers, but put dots for the number over you were, and dashes hopefully for under par. Par's are no dots. You might even change that to a boggie is no dot, and 1 dot is a double (all depending on your hdcp). Then convert to another scorecard the right way at the end of the round.
