Apparently one of the security guards left it on top of the toilet paper holder while he was taking a dump (along with the comics).
It got me thinking about my various safe handling procedures I use in this situation. For me it all depends on what holster and firearm I have.
Shoulder holsters are no issue at all. No prob.
If I am wearing my heavy belt and one of several holsters that have double connections, it's also no problem.
I have several, inside the waistband, holsters that have a single clip and could turn over and topple out if I am not careful. These holsters I may actually take out first. I just hold them while takin care of business.
--I have never come close to leaving a gun behind. Cell phones is another story...
