Has this ever happened to you after being hospitalized and having surgery at a general hospital?

After finishing surgery in the surgical department, when I slowly started wanting to eat meals or snacks, I thought I was still on a fasting diet, but I felt hungry so I just went to the snack bar and bought some bread. In that moment, the guardian, the nurses, and several attending physicians nearby were all greatly surprised and said, "Wait! I believe you aren't allowed to eat anything yet..."
A few minutes later, when the professor in charge came in for rounds, his opinion was completely different. He said..
"No. Although you are technically fasting right now, it is okay to start trying to eat gradually. We can't just stay still forever just because of the fasting order... From now on, if there is something you want to eat, you are allowed to have simple snacks as you please. Instead, you must exercise hard..."
And he added, "Once your appetite fully returns, you can eat regular meals and then go home."
Since the principle is to gradually lift the fasting restriction after surgery..
I remember him saying something almost exactly like that. Have any of you ever heard something like this?
However, if a situation like this arises where there are more than 5 nurses, more than 5 doctors such as interns or residents, 1 clinical instructor, and 1 professor in charge, is it often the case that the opinions of everyone else don't matter at all and only the opinion of the single professor is extremely important?
At the time, almost all the other staff members except for that one professor (there were nearly 10 people excluding the professor) were of the opinion that fasting should still be maintained, but as soon as that one person said it was okay to gradually lift the fasting restriction, they all immediately replied, "Yes, understood."
