Hoo-ahh!
Sorry, folks. Yes the scenario is an entirely hypothetical one in which the gun is openly carried but unnoticed until later. I have to agree with jimdana that open carry handguns absent a badge are something no longer familiar to the general public. There are a lot of hysterically reactive people out there now who can make big problems about it via 911 on their cellphones. Anyway, if you get tossed out on a whim and haven't broken any state laws, it hardly seems you could be required to pay for the meal unless you elect to take it with you.
