On this, and on the point I was making before...
I was sitting waiting for a dermatology appointment. Thank God the receptionist didn't deny I had an appointment that day, which has happened, despite having a letter to prove it!
I was waiting for nearly an hour, and I couldn't help noticing that about every 5th person who arrived at the reception desk was told that their appointment had been changed, and to come back another day. Many of these people had taken the day off work to attend, and some were very angy.
Now, I've worked in admin and under pressure, and I know mistakes are going to be made. But in my jobs I might have made a minor cock-up say, once a week at the most. But every 4th/5th patient with wrong information???? There really is something badly wrong with the NHS admin. And it's not trivial - a lot of money must be wasted that way.
(Also - it was ironic, considering the people they were turning away, that the nurses coming out into the waiting room to call people in to appointments found that at least 2 out of 3 were not there...either through their error, or possibly no-shows!). Yes, I WAS waiting a long time and I did pass the time by taking note of all this!!!!
