Ellylex, tone asside, the reaction here shows you one thing. It seems to be the overwhelming majority opinion that you can't expect anything from LH Customer Service now for what has happened on that flight.

Maybe the FA could have said something to the person to stop the loud typing. But working on a computer, reading, watching TV or screaming (if you are under 2 years old) are things which everyone is perfectly entitled to do on a scheduled plane. Now one can argue how loud the typing can be to be acceptable but the usage of a laptop in principal is not objectionable.

There is nothing the FA could have and should have done other than maybe to ask the passenger to type less loud, if that was at all possible (on my keyboard it is not possible as it makes a distinctive sound no matter how slow you hit the keys).
