Metal detectors are exactly what we used when I was working the front door of a large club approx. 20 years ago...what's so difficult for you to wrap your head around that? The last thing on earth you want in a club or bar is armed patrons and not knowing who is armed or not. I'd love to hear your fantasy scenario of how having a gun in a bar would come in handy...in a crowded room full of moving people...let's hear it.
