Sorry to revive an old topic, couldn't help myself.
When you are late for the game, roll +1 for every 10 minutes late, to a max of +3.
On a 10+ the Host holds 3, on a 7-9 the Host holds 1. The Host can spend his/her hold, 1 for 1 to
• make you pay for the pizza
• make you buy the group sodas or beer
• make you clean up after the group.
On a miss, apologize and try to make it on time next week.
