to quote Hully Gully.
From a news story on the BBC website:
In a survey of 1,000 pupils in Devon, Cornwall, Somerset and Dorset, less than one in four knew that beef burgers are sourced from cows.
Leaving aside the "less than" for the moment, if one must use source as a verb, cannot its use be confined to the business pages along with the rest of the management speak. What's wrong with saying that beef burgers are made from cows. Unless the reporter is suggesting that the cows handed them over with a cheery smile and a side order of fries?
Grrr.
