Rubbing you the wrong way is out of line.
I dont NEED to get to the UK, so I would offer a bump for those very people who need to be back. I just do not want to pay for accoms if I am helping the airline and other pax out, I think that is fair enough.
I may just call ahead and re-schedule though seeing how there are so many holiday makers needing to get home. I do resent being called an oppertunist though.
