Re: Duh!
Wtf is a "chippy" where you come from?
Chippy = carpenter or joiner. That really isn't such an uncommon term, and I think most people would recognise it.
By a similar token, if I had a problem with my electrics and my landlord said he'd send a sparky over, I'd be quite happy about that rather than wondering how some kid with a magic piano is going to make things better.
