Why: A skilled warrior when he wields his racquet.
Unfortunately tradesmen can sometimes be unreliable, i.e. by failing to turn up when they're supposed to, and not all of them are highly skilled, and it's these ones who produce inferior workmanship, sometimes with disastrous consequences - like the joiner who was putting some skirting board in my loo and hammered a nail into a pipe! That said, I have no objection at all to Joe using it because I know he's using it in the best possible sense.
Anyway I can't think of anything myself right now, but Linda's and Angie's seem very appropriate.
