"Presented 0715h-still waiting and very thirsty at..."

I opted to use the accommodation offered by the hospital to allow me to present punctually for my operation-big mistake. I expected basic, clean standards but spent the night in a run down, smelly room with no facilities and no shower, just an enamel bath with a plastic jug for rinsing; not great when you need to use the anti-bac scrub prior to your surgery! I arrived punctually, and waited until about 1030h when I met the anaesthetist and changed into a hospital gown. 3 hours later and i am still waiting, having been told that an earlier operation took longer than expected. Fair enough, but there is no proactive communication from staff-I have had to ask why I am sitting here for so long. I am thirsty and now have a headache-dehydration kicking in, I guess. Why could I not have been offered a drink as soon as they knew there would be a delay? I am praying that the clinical standards will greatly exceed the "care" I have received so far. Please advise how much longer I can expect to wait and whether I will be going home this evening.
