I can well imagine.
As a counterview /anecdote, when I was labouring for my mate's building company there were plasterers booked for a job. Everything and everyone needed to be gone for them to go in. Either the electrician or plumber (can't remember) was finishing something off in one of the rooms. It would have been absolutely possible for them to start at the other end. They just said, "we said it needed to be empty. We'll come back another day." and they left.
