>I had a ticket for five o'clock,
Did you remember to make adjustments for inter-dimensional time?
It was specified in the contract.
Section 2:3.
This would be an error with you. A quick calculation shows it would be Earth time 4:17pm, not 5pm, as you suggested, when the wormhole opened.
Were you standing near to. or in the vicinity of the previously agreed point in space/time when the wormhole opened at 4:17pm?
Missing your point in space/time is not the fault of our Alien operators.
No refunds will be available.
