Two days before admission

I contact the hospital two days before my admission to request a private room and I am finally told the truth; TAC patients are only given shared rooms. I ask if I can pay extra and am told it is $50 a night – a bargain!!! Yes please!! It comes with the disclaimer “if there is one available”. The hospital says if I phone back at lunchtime on my admission day I will be told if I have a private room.
