This is a perfect example of how well-meaning people try to "help" us emets. It sounds like she rubbed her hands all over you to prove to you that your fear is unfounded. She's probably thinking that once you see that you don't get sick even after someone who was sick did that, your fear will lessen. Unfortunately, people like her don't understand emetophobia and really don't know the damage they do when they try to "help" like that. Having said that, I'm sure you'll be fine. Her hands are clean and even if they weren't, you're not going to catch a stomach bug by "it" being on your skin, it has to get inside you, so unless you're going to lick your arms, you'll be fine.
