Correct way to call arbiter

[andyburnett]

The player may stop the clock for anything requiring arbiter intervention. This will normally be done on the player's own time.

Note though that if the arbiter considers the reason frivolous then there may be a time penalty. This could be extra time to the opponent, a reduction of the player's time or a combination of both.

What would be considered 'frivolous' in your experience Alex?
