Generally, in most states, it's legal to carry a firearm without a carry permit in your home or place of business, or to and from those two places.

Your store in a mall might be problematic, again considering state and local laws. Many malls are posted against carrying firearms. Your right to do so notwithstanding, you should look at your lease agreement. In this state, it's illegal for a landlord to prevent any of his/her tenants from carrying a firearm at their place of business.

As to getting caught...concealed means concealed. Keep it out of sight, tell no one that you're carrying.
