One of the joys of public speaking is finding excellent speakers you hadn’t seen before. Dave Lieber writes a column for consumers in The Dallas Morning News. His other web site is Watchdog Nation. Dave his discussed how Starbucks has their own private jargon for sizes that mixes English, Spanish, and Italian.
Watch him in a YouTube video on Dave Lieber & Watchdog Nation Share the Starbucks Secret on TV (including how to drink free coffee there). His demonstration is humorous and memorable. It might be even better if he also pointed out that the cup sizes increase in steps of 4 ounces (a half-cup) as is shown below.
