Zack - sixpence, a deener - a shilling or a bob, that wasn't bastardising of our slanguage. No character or quality was lowered or in any sense debased.
If anything enhanced. And if you'd been the agent who said to the bloke who tried to buy a ticket at the check in counter 'Sorry ocker, the Fokker's chocker', the finer points of language use wouldn't have entered into it.
But your references to 'poseur' and 'arrogance' are offensive, and contrary to the terms of agreement.
