Some clients "may" not want their customers or competitors to know where they purchase their coffee at wholesale. Perhaps this is why you hesitate?
You can always ask clients for permission to mention them as customers of your client. Spin it by saying your client has lots of fans who live in their neighborhoods and could potentially drive traffic to their businesses by allowing you to publish the fact that they use your clients coffee.
Additionally, if your client gets lots of local fans, they might consider selling their coffee at grocery stores or better yet, at wholesale clubs like Sams Club, Costco, BJ's, etc.
