I just had my annual eye exam and the Optometrist has his office in a Lenscrafters store. As I was waiting, I noticed one of these "No Firearms" stickers next to the door. How had I never noticed that before? The corporate office must insist on these things as some type of misguided attempt at limiting their liability. The doctor and I have had numerous discussions about guns, eye protection, and prescriptions to help with aging eyes picking up a crisp, clear front sight while shooting.
If I was ever asked to leave because of my gun, I would happily do so never to return.
