Do I add shadow experience to my new grad resume?

So I talked with Ascension Health + Beaumont HR and they said to add the shadowing experience to the resume for future new grads looking at this post. I just created an additional section: Observation Experience. They also said it could be mentioned in the cover letter.

If you are a new grad student, one thing I was told from an interview that I should add my 7+ years of retail experience because it looks good to them, it means I have the experience how to deal with customers and can work around situations like dealing with angry patients and such. So don't ignore those old jobs, even if you don't remember the manager's name, you can always add the number of the location if you want to.
