Have flown Airbus for a few years. When the PF asked for a flapchange, the mandatory answer for the PNF was "speed checked, flaps…"
After flying mostly Boeings it initially sounds weird, a bit patronising perhaps, but once it has become a habit, you know it gives you just a microsecond extra before your hand goes to the flaplever, and it avoids things like these. It would have felt "wrong" to retract flaps without saying "speed checked".
(Not to start an A vs B fight, am happily flying Boeings again, but it really makes sense..)
