As someone who&#x27;s worked in a Starbucks, they definitely get the points about not forcing jargon and remembering repeat customers; both were mentioned directly in training.<p>I like to spin jargon as a teaching opportunity: &quot;Did you know that we call the large cup a &#x27;venti&#x27; because venti is italian for 20, and the cup holds 20 ounces of coffee?&quot; Now the customer feels like they&#x27;ve learned something about how we make coffee, will use our fancy jargon, and might even tell all their friends that we taught them a snippet of Italian.
