Unfortunately it's more common than you think, especially on the low-tier S SET contracts where you have young first-time Head Carpenters who have the head rush of newly found authority without the experience or technical footing to back up their egos. A lot of them fall back on their macho facade to
cover for the fact that they don't feel empowered to make decisions, and blindly trust that decisions made by the TD and Production Staff were the end-all be-all of decisions and they are reticent to
shift from those plans because they aren't sure in themselves.
