I understand that part about knowing the parts and not being able to guess why some equipment isn't working; customers expect whoever is helping them to know everything. 😅

I would have thought the director was very unkind too if I'd heard him say that to that colleague, but you figured out why he acted that way with that teacher. Like any good director, he knows how his staff works. It was a pleasure reading your post, my dear @sacra97. Good luck in the contest and blessings. 🙏🏼🙏🏼🙏🏼
