Over the years I have flown to and from Palma Mallorca on many airlines. This happens a lot from Palma.
The moment a ground crew turns up at the gate, some busybody has to go and ask something, in many cases irrelevant (I have listened in a few times) then hangs around the desk, prompting others to join them in a queue.
Fortunately, I have travelled with an elderly relative over the last few years, so bypass all the nonsense as we are boarded first. But have had the occasionally dirty look as we walk past the forming queue. I always smile at them.
