As I read this with some nice memories and still a little inexperienced. I would bring her foot creme from time to time, from Aveda, it's good, a little expensive, but they really appreciate, far better than the cheap stuff they use from Walmart and Costco.
You want to encourage a friendship of sorts, give your regulars a little consideration, always provided a good result for me.
The other note, while she's lovely (Lucy is part of a long list really), I don't see her, seems you can tire of a girl, yet still "like & appreciate" them. They work hard for us gents, so a little appreciation goes a long way. Happy Hunting.
