I was referring to needing to high five them. That's a joint effort activity, the GM could easily sway the results by lingering until the player slapped or by 'leaving them hhanging' to avoid providing info.
Something like "putting the camera down, slapping the table with both hands, then snatching the camera and taking the shot" would be totally in the player's control. The inclusion of GM participation suggested a possible control mechanism to limit how much / when information gets provided.
Which is cool, if that's the intent! I was just curious if the enhancement of GM arbitrage was a feature or a potential issue.
