"Awful"

Had a blood test booked for 4:50pm as I work until 5 so I had to book last appt and finish early. Got to the desk at 4:51pm as the parking machine was awful (£3 for 1 hour parking may I add) and they refused me my appointment. All standing around watching tv had 2 kids with me just awful service and will never book again. No offer to accommodate or rebook - nothing
