I was watching Star Trek Discovery, and Michael was running from the bridge to engineering cause Tilly was in trouble.
But it did spark a question. Is there a rule against using transporters within the ship to get from point A to point B? If you need to get there fast, like a medical emergency. I don't recall ever seeing that, but I decided to ask, cause I'm sure other people know more.
I know in ST:TNG, there was the convict who was escaping who did inner ship transport.
