You are right, never been to Leuchars probably never will, but would have no problems buying the blokes a beer and joining in with some banter, Im sure they would take it in the lighthearted banter form that it was intended.
If they did take offence I would simply drag them outside by thier nostrils and point out the errors of not laughing at my opiniated jokes
Ill also travel to shawbury if you like and tell A2QFIs wife she is a snarling gripperfish too
