I work at a bar and wonder about damage control?

I saw a young lady(I believe she is 25?)- and I do believe she is a lady- come i with her parents, as they have been doing for over a year. She usually doesn't drink much more than a couple of beers but this night someone bought her a few shots and before long she was very intoxicated. A man she likes (and has possiblly been seeing?) for a few weeks was also hanging out with her and her parents and the two snuck off to share a kiss in private. He is also a pretty good guy who her parents like. No one but me saw and they returned to where her parents were. She was loud but exxagerated her movements but didn't get sick and didn't even swear. I know this family pretty well and her mother is very judgemental and I wonder if there is anything I can do to help her do some damage control. I know she is embared but she has been a very good tipper and is always very kind to help us clean up and I want to help her if she needs it.... any suggestions that dont make it look like i am a chasing after her?
