Two points. (1) I've been to the facility twice in past month. Both times, at check-in I got in line behind elderly people (I'm 65) with no clue how to type their name and birthday into the mandatory check-in screens. After many minutes of waiting a hospital employee had to come out of her workspace to physically assist the patient in typing in his or her name and birthdate. If you are treating an old population, do not presume they know how to use even simple technology. (2) the person booking my ct-scan appointment obviously did not read my doctor's order and gave me wrong instructions, including telling me to arrive more than an hour necessary. You cannot give people back the time you take from them.
