I went to UMC with severe breathing problems. 
I told the receptions I have asthma, and probably a lung infection.
I also told her I was unemployed, uninsured, and I'd have to pay cash.
The receptionist said it would cost $95.
A nurse checked my blood pressure and told me to relax, she put me in a room and gave me albuterol nebulizer treatment. Later, another nurse came in, and she took 2 X-Rays.
Doctor Fellows came into the room and said I didn't have cancer. Okay...um.
He gave me a prescription for 5 antibiotics (I specified Erythromyicin) , 1 albuterol inhaler, and albuterol for my nebulizer.
He told me to see a Primary Care Physician with one week.
When I left, I went up to the receptionist, and paid her $95.
The receptionist said I'd get an invoice in the mail in two weeks.
