I totally concur with
BOAC.
da42flyer may well have had a taxy clearance to the gate. However, with another aircraft potentially converging from one side following a landing roll-out, almost certainly on another frequency (TWR) from me (GND), I would have stopped as well - and I believe any professional airman worth his salt would/should have done the same. It could be argued that ATC should have anticipated this possible confusion and clarified which aircraft was to give way - but it seems that two different frequencies were involved and this was definitely the fail-safe option. Certainly no blame should attach to either pilot for the ensuing go-around.
By comparison, I feel that
Tower Ranger's attitude (above) is an accident waiting for somewhere to happen.
