I accidentally saved a kid today and I can't tell anyone

I'm a 17 year old barista. This morning I had a regular (who is a young teen girl, looks like she's around 13-14 years old). Anyway, this morning she did not seem right. She was really quiet and I asked her if she was ok. She told me she wasn't feeling good and I told her that I can annul her drink for a refund and she can go home and rest. She told me no, I Insisted, and she eventually left.<br><br>A half hour later, a mom came in and ordered a drink for her kids. She was chatting with one of the workers and I overheard her talking about how her daughter is charting with NPD and that she took her to get a morning drink out of habit. They walked out a few minutes later leaving their drinks and Sid the mom didn't take them. Long story short it was next to me and I finished it so it wouldn't go bad.<br><br>I honestly did it out of good manners but the girl has looked out the window every time I'm not looking and I can tell she knows it was me. And I don't know how to feel or what to do. I saved a kid today but I can't tell anyone.
