If you read the news article it was not a pee that he was desperate for, he had eaten something that upset his stomach, you know what i mean ? He asked the attendant if he could pass the trolley in the aisle which was blocking his access to the toilet in his class of seating and in desperation he ran for the business class loo.
If i was a flight attendant i know i would not have liked the clean up job .... and would have been more customer orientated.
