DOUBLE LIKE
At our place, the radio rarely gets answered. For some reason F/Os love to demonstrate how fast they can call, sometimes before retracting the flaps and whatever else they do over there as part of the after landing flow. Like...why? It isn't like the below wing staff are anxiously awaiting your call to sprint out to the box with lighted wands. Even if they were, does that extra 20 seconds really matter?
But I'm an easy going guy, so I usually say something like "the Company appreciates your efforts" or something along those lines. Don't want to fall in to micromanagement territory.
