So I'm in Jessops looking at their list of film scanners and other bits
and bobs and there's a person buying a Canon 20D at the counter. The
salesperson goes through all the spiel, puts a lens on, powers it up and
hands it over.
The person holds it at arm's length, points it at a companion, looks at
the LCD at the back and says "This one's nacked" (= broken)
