Previously walmart's corporate policy was that CC was allowed but if someone saw your weapon you were asked to leave. Now it's not a corporate policy so it's up to the managers. If I was a manager there I would of apologized to the older gentleman for you being an ass and asked you to leave.
Actually Walmart's corporate policy is to now mirror state law the store resides in. But not all managers know corporate policy. If confronted by store managers and ask to leave, then get manager's name and leave. Then contact corporate lay the full story out to them, most times corporate will contact the managers and inform them of their policies and have them inform/train their employees of said policies.
