A couple of times I have seen photographers leave negative feedback just because a model has dropped coms, or not replied to a message or two. Provided it wasn't last minute, and no one has lost time or money, isn't this a bit much? what you read is "how dare they ignore my TFP offer/money."
It happens to me fairly regularly that a shoot is under discussion, but doesn't happen, but I try not to lose sleep over it! Are there some fragile egos on both sides of the lens?
What's your best fragile ego story?
