"Appointment times"

My appointment @ Medical Outpatient Dept: yesterday with a Respiratory Consultant was for 4.30p.m I was eventually seen @ 6.40p.m. Appointments for patients were for 15min: intervals, but were taking 30-45mins, therefore obvious delay backup as day progressed. Due to tests at 2.00pm of 90 mins (which were dealt with in very good time) and the above we were in the hospital for 7&1/2 hours. Whilst my treatment was 1st class your appointment system is ridiculous and suggest you update them, there were a lot of very tired and cross people in your blue waiting room.
