What kind of "referral" do you need/can you acquire to get into a place like this? Do you have to mention somewhere else you've been? How could anyone verify that? Do they call each other and ask "Have you ever seen [this guy]?" Who could even answer accurately, when they see so many [this guy]s all the time? Sorry for so a many questions, but this confuses me. I like walk-in places best, but I'll make an appointment when I have to. But filling out an application and/or collecting references is a bit much.
