Poor sod. Who would you claim against if you got a flat tyre driving to your meeting, and missed the meeting. Stuff happens.
Stuff does happen, but ultimately someone is responsible, in this case KLM. I have no qualms about claiming the compensation to which I'm entitled.
The one time I couldn't claim was when some selfish person jumped under my train as we hammered through Stevenage. The ensuing delay cost the company I work for around £1.8 million pounds for a lost contract. The train driver was so traumatized he had to be removed and replaced, while the body parts were rinsed away.
