I have.
Operationally critical part (something do with a gearbox) to be delivered to NIPV at anchor on a Saturday morning by RAF Wessex. Phone call taken - direct quote - "we're having a dining out [friday], could we bring it on Monday instead?".
That's not intended to knock the Crabs - they did a fine job on the whole, but to say they were as efficient and flexible as the Junglies is not the case in my experience.
