Exactly. I don't think I would be comfortable with that kind of banter, it sounds too flirty to me. But some people, I imagine T's also, do not intend flirty-ness to be predatory or to make anyone uncomfortable. I think T's need to be extra careful on the flirty-ness scale because it can promote sensual/sexual feelings in clients.

Once, my T called me "sweetie" but it was clear that it just slipped out and he didn't even notice himself do it. I think he was just feeling very tender towards me that day, maybe a little over-protective. But if he did it repeatedly or it seemed like a deliberate strategy that included the kinds of behaviors and statements you are talking about, I'd be very uncomfortable.
