Why is it called Doctors Urgent Care but takes FOREVER?!

So for my new job as a preschool teacher I had to have a physical and some booster shots done. No big deal right? Ha! I first went to my county health department (because I don't have a family doctor because of my insurance, it is very hard to find one that will take it!) and they told me that they don't do the shots for anyone under 18 unless I pay for it and they are pretty expensive. Ugh! Well since I had to have a physical done too I just figured I'd go to the local urgent care center (where they also do physicals, etc) and get everything done at one place. I get there and they tell me it's going to cost $90 for the physical! Since so many insurances don't cover routine physicals they make everyone pay for one. Well, that just stinks because I don't know if my employer will reimburse me! So anyway, I sign in and pay for my physical and sit in the waiting room. Twenty minutes later I am being called back. Now let me just say there was no one there! So waiting 20 minutes was just ridiculous! After being called back and explaining to the nurse why I was there, I sat in the room for a half hour! Yes 30 minutes before the nurse practitioner came in!!! Then he does the physical thing and I ask him about the immunizations. You'd thought I asked how to end the war or something! It was ridiculous! Finally they come back in and tell me that I can get 1 vaccine there but they don't have the other one, I have to go to their other office (25 minutes away) to get it and they have to do a blood test to see if I need the 3rd booster so I have to go back on Monday for the results of that and get them to sign the paper saying I got all this crap down and I am physically fit for the job! Aaaaaggggghhhhhh! And this is all for state requirements! It's ridiculous! So needless to say I spent over an hour at this "urgent care" place that was not busy and I am still not done!
