<human>: I've [25/M] met this girl [20-21?/F] at my office building. She works as a barista in my office building and I frequent that coffee place regularly. Over the past few days I've come to talk to her more and in the process getting to know a little about her such as her name, education background, near-future plans, etc.

We are by no means considered friends yet but she does remember my order and we do greet each other whenever we bump into each other (we park on the same floor of the building).

I plan to ask her out but was also thinking of leaving a note on her car (using a receipt from my earlier purchase at the coffee place). The note is just to say thanks for the awesome coffee and that she'd have a wonderful weekend.

My dilemma is would it be seen as too much or creepy? She knows that I know which car she drives as we've seen each other in our cars while parking before. That being said, would it still be considered OK to leave a note on her car?

Can you condense the text into a few key points?
