Often enough that it's a time saver to start with that person's coloring. And yeah, it's usually not a man coming in alone, unless he's single. If a couple comes in together, she goes with the coloring of the woman, because they tend to be the decision makers, with the men having veto power. But when she talks about seeing people I knew in high school, she usually identifies the woman as having come in the store.

I don't think she has a script for dealing with same-sex couples since they're pretty rare out there but my guess is that she would probably work with whoever engaged her first.
