Great! This sort of "interactive link" is polite and what I wish more websites would adopt instead of cluttering their site with fixed positioned widgets. A good example is chat widget. Instead of using a fixed positioned chat widget that annoys your users (esp those on mobile), why not stick to good old "Contact Us" link that opens your chat widget only when it is clicked.
