Funny as it may seem I have never been in an escort situation where I have been referenced as hun, honey, babe, darling, etc.
However, as mentioned by @azdr0710 I do like it when a waitress uses the term “hun” or as happened earlier today when I was referenced as such by a young lady who wanted to make sure I had found everything that I needed in the garden center at Lowe’s. It adds a nice personal touch to the experience.
