Sounds like the reasoning listed in the original responce was that their employees are not allowed to be armed so the 30.06 signs were posted to protect their employees from armed customers!
"While there are probably many responsible members of society licensed to
carry handguns, and you no doubt are one of them, being the employer
of 100 plus non-armed employees, I do support my businesses decision
to post that signage."
This is just another example of liberal hypocracy, par for the course.
