Reason to keep hiring?

I've been a month in a dealership of a Japanese brand and see that they keep bringing new people on the floor. The old staff is still there. The dealership is relatively small of about ten salespeople before add-ons. Now it's thirteen and counting. They introduced for the first time, a month-end new car sales volume bonus. For them to even out it makes sense to flood the floor to prevent too many folks hitting bonuses, at the same time creating edgy competiveness among sales folks. Having said that, the traffic is slow and one has to be on a lookout to grab anybody out of nowhere, we have three entrances. A question to experienced folks: do you prefer a one rock solid entrance and an up list or a chaotic grab from anywhere scenario? Please forgive my naivete, I'm not new in sales but car sakes is still a very uncomfortable environment for me.
