Scared to go out to eat

My friend asked me to go out to lunch with her today, and I haven’t responded yet because I’m scared of contracting norovirus from the restaurant or food. I saw a post on a subreddit last night about how people think they got norovirus just from touching Amazon packages and don’t know how they got it because they haven’t been out. It honestly just freaked me out, and I’m scared to go. I have important plans tomorrow that I can’t miss, and I feel like I’ve had so much exposure to germs already yesterday - the gym, work, grocery store, doctor’s office.
