(d) An offense under this section is a Class C misdemeanor punishable by a fine not to exceed $200, except that the offense is a Class A misdemeanor if it is shown on the trial of the offense that, after entering the property, the license holder was personally given the notice by oral communication described by Subsection (b) and subsequently failed to depart.
A good DA would be able to make the case that he was orally notified and that any time he comes onto the premises with a concealed handgun, he has failed to depart after having been orally notified. Simple matter though. If the OP is caught, his manager (or someone with apparent authority) just has to say "get out now, you know that guns aren't allowed here" and then it would certainly be a Class A if he doesn't leave immediately.
The law is quite clear: AFTER ENTERING THE PROPERTY(with a handgun), if the person is given oral notification and fails to depart, then they risk losing license with Class A charge. Until then, they face a Class C charge, if it can be proven they were indeed given notification.
