You say you can question the referee's judgement when a warning for stalling is given. I say that is true in certain circumstances as explained by Will.
On the other hand, if you think he should be calling stalling but isn't, there is no such warning and thus no opportunity to question his judgement. You can only sit there and say "He's stalling". "He's stalling." "He's got to use that." "He's backing up" "That's stalling." "Make him wrestle" "Come on ref, this is getting ridiculous" "You must be blind" "You son of a motherless goat"
