Super true and ask in
advance. One show I worked, there were flats that didn't fit in the freight elevator, and it took special permission to bring them up the fire exit staircase and through the
house.
Since the scene shop knew what
theatre they were building for and had all the dimensions ahead of time, it would have been prudent to ensure the set could be loaded in.
On the other side of the coin, I worked at a
theatre with a strict no food policy. Not in the
house or
lobby or backstage. The only place you could eat was in the bar, but the bar didn't open until the
house opened. I was mixing and came from work so would usually pickup a sandwich for dinner on the way.
Thankfully I didn't ask about the food policy so I didn't hear about this rule until closing weekend, so I only had to endure 3 days of eating my sandwich on the streets of San Francisco instead of with the crew at the backstage
tech table.
