First of all, you don't know for sure that she even saw v*. There are a million different things it could be, especially in a restaurant! People take their leftovers with them when leaving and often run into the restroom before they go. I've seen people drop their little boxes and bags in the stalls before, so it could have been that. It also (more likely than a sv*) could have been a bulimic. If it even WAS v* it could have been a person with cancer, pregnant lady, etc. V* doesn't mean sv* MOST OF THE TIME. The chance that it was something contagious is really, really slim. Even if it was she didn't touch it and I'm SURE she washed her hands. The chance that first of all it was a sv*, she touched the same surface as the individual, didn't wash her hands well enough, carried the germs to you, you happen to touch the same surface and then touched your mouth is SUUUUUUUCH a stretch I think you should forget about it! Really.
