but ultimately someone is responsible
WHY???
Why does there always have to be somebody responsible?
Why can't things just happen? It's unfortunate when they do, but ultimately in life things do just happen.
Why can't we accept this and move on, we all get delays occasionally, but whilst they are frustrating they are just a fact of life, whether that be a plane journey, train, bus taxi etc etc.
This WILL undoubtedly result in higher fares, the costs have to be covered somehow, and as ExXB states these costs are very high, and are commonly double what he quotes as there is often another load of passengers affected by that initial delay.
Here's hoping the rule is scrapped!
