I was there during that discussion. The cleaner in question is up front with the client over the phone about the vacuuming. If the client doesn't want him to vacuum, he doesn't. If the carpet really needs it, he will vacuum anyway, and not charge the customer. (client either doesn't know how to vacuum correctly, or their vacuum is a POS)
I personally think that the price should be raised, and ALL jobs get vacuumed.
