Yesterday the wife and I went to view the opening of a new wing at one of the local hospitals. Of course, I took the camera with me, and after firing off five shots, a security guard pulled me aside and asked if I had permission. It was my first time experiencing this, and of course I told him no, that I didn't know permission had to be recieved. He was quite nice about it, and informed me that due to 'security and privacy issues' I had to contact the hospital beforehand to recieve permission. No problem, I told him, and put the camera back in the bag. Anyone else have any recent dealings of a similar nature, and how did it go?
