Dr. Chow was great. However, yesterday was my second experience with the lab closing early. My appointment with Dr. Chow was at noon. At 12:17pm, he sent me to the lab to have some bloodwork and an x-ray, unexpectedly. When I got down there, the security officer informed me that they closed at 12:15, when their posted closing time Is 12:30pm on Saturdays. The first time this happened to me. The lab closed at least 15 minutes early during a weekday afternoon.
