Listen, you have to be pretty dense to conflate questioning the recounting of a story with a justification for gun play.
We are just supposed to believe every tom dick and harry and the stories they tell on the internet?
The point is, flashing a gun is so uncalled for that it lends itself to ribbing the OP for his recollection of events. There was potential for humor here, if 1) OP could take a joke and 2) everybody's panties weren't so scrunched up about guns.
Anyway, no harm meant, OP. Be careful at the gas stations.
