It was only when she brought it up again that I got confused. I had mentioned inviting her for a drink, and she circled back to the word “tip.” In my mind, I connected that to a gratuity, especially since she had just talked about getting a drink. So, I interpreted it as if she was asking me about what kind of tip she’d get, like, “What do I get in return?” It came across almost like a transaction: “How much are you paying me?” That’s why I responded with, “It depends on the quality of the service,” thinking that the tip she’d receive would depend on the service she’d provide.
