The other night my wife and youngest son were sitting in a Wendy's eating dinner. I was not carrying as we were going to be visiting my son's school immediately afterwards.
About halfway through our meal I overheard loud voices at the counter. I couldn't make out all the words but a male customer was accusing the cashier of ripping him off $10. The customer walked out the door and into the parking lot out of sight.
Of all the approximately 10-12 customers in the store only myself, another man waiting at the counter and possibly a woman seated over a wall next to us seemed to go on alert and watched for the man to re-enter the restaurant, which he never did. I also did not hear any actual threats verbalized during the argument.
We continued eating and later into the meal as the woman next to us was leaving I overheard her telling her young son what to do if someone entered with a gun (get under table, etc.). My wife and son and I had the same conversation, but it was clear the other woman had appraised the situation as possibly threatening (maybe a fellow CCW'er? It looked like she had a fanny pack on).
Anyway, nothing happened but I was wondering what would be the threshold for taking your family and getting out of dodge? Shouted threats, customer re-entering the store, or display of weapon (little late there).
Looking back maybe I should have gone to the window and made sure he drove away and not retrieved a weapon. But given no threats were made, it might have been over-reacting.
