So last night was tournament night at my FLGS, and I wound up getting paired with a player that I've played a few times now. In previous games, he would conveniently sloppy when it suited him, avoiding bumps and rocks by not quite placing the template or ship.

Last night it was a whole new level. After I moved one of my ships he picked up his dial for a ship that hadn't moved yet "to see how screwed I am." And then he started thumbing the dial to a new maneuver.

I know that no one else saw it, and they've been playing at this store longer than I have, so without proof, if I said anything, I would be a troublemaker.

How do I handle this in the future?
