They could have had ground staff at STN
Have you ever dealt with ground staff at Stansted??? They have six toes at least!
In fairness sounds like flight deck were a bit busy but that's no excuse for one of the two picking up the phone and giving an apologetic tannoy. It can make ALL the difference between feeling inconvenienced but in the know and hacked off, baffled and angry. It's not rocket science, and whereas I can understand that the handling agents being paid piss poor rates have almost no leeway for diversions to be handled well, especially from non based airlines, paying someone loads of money to go from A to B and being dumped at C with no real explanations ( operational reasons is not a intelligent reason..... ) is the quickest way to lose your customers to the opposition!
