As a doctor who works with patients with cancer I on occasions have to tell patients they have terminal illness and there is no treatment - people handle that news differently - how would you appreciate it if I gave you that news and while you were crying and wanted to ask questions I said “you have to leave now as I have another patient” - clearly that would be inappropriate - alternatively booking every patient twice the expected time to take into account the possibility you needed time would mean poor use of my time and a longer delay for patients to be seen.

In a public situation if there was compensation to be paid to the following patients should someone else miss out on a health service because money has to be paid. Or in private should you have to pay for all the following patients compensation because you had struggled with bad news - would seem very unkind to get news of terminal cancer and a huge bill!

There are so many situations which cause us as doctors to run late - if you had a difficult problem which required tests to be arranged and that took some time would you be happy if you had a potentially preventable poor outcome because everything had to be left to another appointment in several weeks and by then it proved too late.

I could give so many more examples but hopefully I have made the point.

The naivety of your post is so irritating.

The reason for Airlines having to pay compensation is somewhat different. Many delays come about due to things like known crew rest periods, the frequency of quick plane turnarounds, lack of spare capacity etc which can be managed by a business to minimise risk of delays - the compensation rules are a deterrent to running things too close to the line.
