"Appointments time delay"

Not for the first time have I attended the Hospital for both x-ray and blood test. X-ray is always available within a short waiting time but today my blood test appointment earliest date was in eleven days time. My next Doctor appointment (for results) is in nine days time. I drove to Crawley Hospital,had the blood test within two minutes of arrival because of the non appointment,ticket queue system. Is it not time the Horsham Hospital changed its' system for the benefit of patients rather than the convenience of staff?
