Genghis, that's a tiny part of my reason for not returning. My decision was made long before then.
The warning was meant to be a genuine one as my friend was assured that there was fuel available when there wasn't and the enforced delay meant landing time at the destination meant the onward flight was compromised. I have no idea if fuel would be available at Full Sutton but that could be a planned alternative if it were. I would hate to see that happen to you and everyone else.
