Wow, I'm bowled over by your kind and generous offer, would you like free fitting on that and a 10 year guarantee?..
Hang on a minute, I've just come to my senses, this isn't such a good offer after all, you bounder! You nearly tricked me with your charm offensive and deft negotiating skills. By baffling me with your big words and elongated sentences I nearly sold you something for a fraction of the price and paid for the privilege of posting it to you.
Shame on you Sir...
