I was contacted through two channels asking if I was available to pick up the 601 from Luton. Neither of the intermediaries knew that I was already owed money by Bexair, so were surprised at my declining. ( I couldn't have done it anyway as I'm busy at present, but that's not the point).
If any UK residents who are owed money want to PM me, I have been looking into getting a court lien applied, which means that next time the aircraft lands anywhere in the UK it is impounded until the company either pays up (money plus legal costs) or demonstrates in court that it doesn't owe the money. I'm not worried about the second possibility!
