At the risk of being bashed, I think it depends on your definition of flirting. If he has a "social job" then he really has to be friendly. So it is a fine line between friendly & flirting. I think the latter implies sexual overtones, in which case, if that bothers you, he should keep it friendly, but not sexual.
He really could mean nothing by it. But that's not the point. Even if he means nothing by it, it obviously MEANS something to you so he should respect that.
