I can see it now……….
Hello, this is crewing. We need to call you out. Can you please be here in 90 minutes as per your contract?
Well, I will do my best but I will need to consult the bus and train timetable and I will then be able to give you an ETA for my arrival in Ops.
Oh, by the way. Presumably all the passengers are there having parked their cars in the various long stay car parks.
I rest my case!!
