Violation or Absolutely Nothing???

Yes - probably ignore B's action and call the 5 seconds......

With situation like this, we want to remind ourselves to discuss the topic of returning the the floor after 1st horn to the coaches during pre-game. Had the coaches been reminded during pre-game, you have every right to use the "resumption of play" procedure to penalize the team that take their sweet *** time to return to the floor. I don't feel bad for coaches who try to take advantage of the game.
