I recently needed laser eye surgery. The surgery was performed exactly when I'd been told it would take place. There was absolutely no waiting around cooling my heels in the waiting room. And not because my doc isn't in demand, but because it's a well-run practice.
You'd better believe I posted a glowing online review the minute I got home.
Don't just write about those rude docs on Medium -- although I love your writing. Make sure to write reviews on both Yelp and Google calling them out.
Critical reviews make a difference.
