Thanks but no-thanks Zlin, I think a precautionary landing would have resulted in a chat with the CAA and a letter of explanation.
A word of warning, if they think that you have been a bit,...er...how shall we say...dodgy, they will report you to the CAA in a flash.
I think it is a bit harsh to say they are all tossers, I blame the management for not supplying enough staff. We all need a break once in a while.
