I know everything is contextual, but should I eject immediately after getting the #close in day game?

I recently got a cashier's number, and HB 8, and I said "I'll see you soon". As I turned away it looked like she wanted to talk more, but I was already in the process of leaving. I just texted her a few minutes later with a flirty/funny message and she replied 'haha, glad I could help'. So all is well, but I'm curious what you guys think. Should I leave, letting her wonder where I'm going and have the last interaction be a positive one, or stay and try to chat her up more?
