I recall an incident on BA some years ago when a passenger was verbally abusive to a stewardess, but in the end it turned out quite amusing.
The aircraft departure from a very snowy Malmo was delayed by late arrival from Heathrow which had experienced its annual 1 inch of snow.
The middle aged businessman was telling the poor young lady what he thought of BA punctuality. She looked like she was barely out of school and from the expression on her face I thought she might burst into tears.
However, she apologised profusely and then added "and would you believe, half way across we had to get out and push".
Loud laughter all around and not another peep from the man.
