Risk related pet peeves...

Mine absolutely must be people who turn in sets during the final stage of the game.
Here's what I mean by final stage.
1st stage: Beginning: Everyone sets up what would be viewed as "their territory" or the place where they plan to build.
2nd stage: The game commences in the game we all know and love... Risk.
3rd stage: clean up: down to 2/3 players and 1 player has all but 5 or 6 territories (on a normal sized map ex: classic) and just need 1 more turn to finish off all opponents. the opponent (assuming this is flat rate) turns in a low set and spreads out to about 12 territories, just making a bigger mess to clean up. The worst part, he wasn't REQUIRED to turn in a set that turn.
