Haaah...who knows? Sakaki would probably leave them alone/ignore them while doing his taxes in the back, then tell them to scram a little while before getting his massage...mainly because after hour three of a long massage session, he starts cussing up a storm. Then he's all happy and mellow again the next day. This is only once a month thing, the rest of his visits to the hostess club is just to drop in and grab a cold tea before heading home.
