"Good Service but unacceptable wait"

Ii have been visiting Salisbury Hospital for many years and am in the Autumn of my life, overall I find the care and service at Salisbury Hospital second to none. However - I would like to point out one thing that I find really unacceptable: I regularly attend the Glaucoma Clinic for check ups and have an appointment which last approx. 10 mins but when I arrive my notes are put in a tray and then everytime another patient arrives the notes are placed on top of mine and then the next patient taken in is the one on the top. This means that having an early appointment results in being at the hospital for hours. I do not like to complain but this time I waited for two hours - which at my age I find difficult. I hope that this situation might be looked into. Thank you,
