Once I arrived and were told the place was not taking any more walk-in patients, I would have asked a few questions, followed the reasonable part of their instructions (go online and make an appointment which I would try to do onsite; the midnight part is unreasonable), made note of the surrounding and environment, observed whether something was going on that made for this chaos, and made a detailed report documenting all. You will have had the true patient experience.
Going back for seconds would involve a second fee.
Oh, I had the true patient experience and they said they wanted to see how they handled walk ins so I think I should get the full fee I negotiated.
