Okay... Shawty is fine. Freak is fine (if in bed), but honey, doll, sweetie, and like terms are only fine if you're in the inner circle.
The further south you get, especially in the service industry, the female servers call most everyone "sugar," "honey," etc.
There are a lot of cavemen still out there. This doesn't surprise me at all.
I've been trying to avoid "guys" and use "folks" or "everyone" instead.
