Another true story:
Around the turn of the century I was part of a group that examined candidates for postgraduate qualifications from the Royal College of Surgeons of England.
On the final evening the dozen or so of us would go for a group meal and each examainer's individual food allowance would be pooled for one big blow-out. Sadly, alcohol could not be claimed against this allowance but there was no limit (within reason) for food.
So at a Chinese restaurant somewhere in London the chief examiner asked for the bill but said to the waiter:
"When you make up the bill, instead of itemising the beer and wine can you put it down as food?"
"Of course, Sir."
When the bill came the final lines were:
6 bottles red food - £xxx
6 bottles white food - £xxx
12 pints draught food - £xxx
