How to deal with travel delay

It was a bit of a disaster with delay and such on my Eurostar trip from Paris this morning.
I thought it may be good to discuss how to deal with the travel delay.
1) Stay calm (Keep an eye on your luggage, passport and wallet. Losing them is worse.)
2) Think of alternatives if needed.
3) Check if there is compensation from the travel provider  (yes, it is important)
4) Don’t get upset once you have established that there is nothing can be done by you but wait.
5) Make the best use of the “extra” time. Have a drink/coffee and/or read a book/magazine.
