Dixon could not personally say anything to any of the crew.
I will fall over if he does, he possesses neither the humanity, humility nor personality to speak to anyone face to face....
I hope he does go and shake all their hands.
That is the Captain, F/O and S/O (or 2) and indeed ALL the cabin crew. To do that would mean "engaging" with the staff. The Oldmeadow playbook doesn't allow a thank you to staff....
