I've heard of another incident there where another student (not me) was given a bollocking a while ago on a land away to Cumbernauld after some confusion about ordering in the circuit.
I heard it second or third hand but I think he did a much tighter circuit than one of the locals and ended up in front of them without seeing the other plane. Was it his fault - probably but there are ways and means, and no harm was done.
He was pretty cut up about it (he might have got a lift back rather than flying back to our club) and it knocked back his training quite a bit.
IMHO the radio is never the right place to give out a bollocking (why not just ask the pilot to contact / phone them back when they land?). I suggest it is actively dangerous to stress the pilot (esp if they area student), as if they focus on that issue then they wont be concentrating on the flying.
