Sorry you are going through this. What a horrible experience.
I would be so ticked off especially going through getting the IV. If you have problems like I do which it sounds like you do I would have been furious to say the least. I hate needles also. They freak me out.
If they came in to tell me surgery was off until tomorrow I would want to know why. Don't tell me you don't have a piece of equipment because that sounds like a BS story IMO. Just tell me the truth & be upfront with me.
I'm with Laura someone probably had to much sauce if you know what I mean.
They would not be charging me either. I would tell them don't bother billing me for anything you did today as I did not have surgery & am not paying for it twice.
