There's no way to tell based on this one conversation wether she likes you.

However! I've worked in retail and now at a hotel, so I work with customers/guests. I do not chat it up with people I find to be creepy, unpleasant, or unfriendly. So it probably means she thinks your normal/likable. that's atleast one good thing, right?

chat with her some more on your visits and see how it goes.
