"my stepfather had an appointment at the..."

What could be improved

my stepfather had an appointment at the eyeclinic for 12.30 he was asked to return at 1pm so had lunch and went back(it was a routine op just an ingrowing eyelash removed) he arrived home that night at 20.30pm - eight whole hours at the hospital he is 76years old has heart failure and is diabetic I was appalled that you had given everyone in that clinic a 1pm appointment what a ludicrass system surely someone can come up with a better method and why didn't they ask him after several hours if he would prefer to have gone home and made an appointment for another time (which he would have had the same problem with I presume)

However he did comment on how pleasant the nurses and doctors were

But please get your act together Macclesfield Hospital
