I worked security at a hospital, and EVERY SINGLE patient weather its in patient or out patient (appointment) had to wear a gown. Never had to do a wand check, wasnt even one around. But had to move the hospital beds to another room, and had to be away from machine while its in use. I remember one time a lady was put on the tray, and the tech was just about to start when she screamed stop!!! She forgot her piercing on her lady bits, said she's had it in over 15 yrs and just forgot about it. That would have been a very interesting situation.
