I needed to get from Portland to Eugene. In Oregon, there's a bus service that's paid with some state funding that goes from train station parking lot to train station parking lot. I wanted to use the restroom at Union Station in Portland and the security guard required me to show him that I had a valid ticket to stay in the building. So it was kind of like what you are suggesting.
