Sorry xoxoxobruce, my sincerest apologies. You're quite correct. I failed to check the nationality of thrillhouse and speed read my way through the prior posts. Unfortunately, I'm using my Mac at work when I'm in the Cellar and have to dodge my boss when doing so which sometimes means I don't pay full attention to what I'm reading.
But, before reading those posts I had been on some other threads where I'd come across a couple of genuine sarcastic swipes at us Brits and my dander was up. Third time round it was a case of what you call 'three strikes and you're out' moment.
Besides, I thought the smiley, and the fact my riposte was so obviously crass and stereotypical of insults aimed at Americans, gave a clue that I wasn't being too overly sensitive about the comment. Friends?
