I worked in pizza delivery once upon a time. I also have worked for a couple of major retailers. I did work for Papa Johns for a while and they had a no gun policy. I choose to go ahead and carry though, if I had to use it and got fired and lost my $12 and hour atleast I would still be alive.) Like others have said, I don't think that it was so much that they are anti-gun as it is that they were looking to not be liable if someone representing the company were to shoot someone. Both of the retailers that I worked for allow customers to carry guns but forbid employees for doing so, on or off the clock, for the same reasons.
