I understand the gentleman's dilemma. Sometimes you have to think past stage 1 (though with a groin injury that pretty much trumps anything else), and think about other priorities. In his case it was probably a strong dislike of hospital food. Personally, I think hospitals are full of sick people and I try to avoid them if possible.
NOW, I wasn't shot in the groin, but, I had a rather nasty industrial accident which needed emergency room treatment. So, of course, I drove myself home, showered, put on clean underwear, then drove myself to the hospital. Once they got me on a cart, I went into shock.
POINT:
There was no way, at 18, I was going to the ER, where all those very cute nurses were, with dirty underwear and not looking and smelling my best. PRIORITIES.
And yes, I left there with 2 phone numbers, both of whom help ease my pain and suffering over the next couple of months.
