I left my number in a letter for a restaurant hostess...?

I was at a restaurant on Sunday night with my mom for dinner. We got seated by a very pretty hostess. I thought I was just going to leave it at that, but it turns out that she was passing by my table a lot and staring/looking at me many times. She didn't even make it stealthy either, she made it obvious that she was looking at me and nothing else. My mom also noticed she was staring at me before we were seated and at the times I didn't see her staring myself. Even on our way out she looked at me with wide-open eyes and a slight smile.

So the next day (yesterday) I went back there myself with a brief enveloped letter I wrote for her. Basically telling her who I was and how she was really pretty and to call/text me at my number (no pressure though). She wasn't there, so I left it to the 3 employees at the desk to give it to her when she came into work, which they agreed to.

I haven't heard anything back as of now, but I'm curious about something. What do you guys think happens in a situation like this? I'm hoping they remembered to give her my note, or at least they may have a back room where they leave stuff for employees which she would find eventually... What do you guys think?

Thanks for any conversation/opinions.
