The following experience I had in a coffee shop recently is a classic example of the work ethic sadly prevalent among young people today.
Coffee shop girl: "Hi, what can I get started for you?"
Me: "Can I get a small dar...."
*turns around and starts chatting to her friend*
So rather than cause a scene - which believe me I am THIS close to doing - I let it slide.
Me: "Can I get a small dark roast please"
Coffee shop girl: "Sure! Let me get that for you."
She then turns around and walks TWO FEET to the coffee machine, a journey of approximately one second.
Coffee shop girl: "Did you say a light coffee?"
Me: "Dark roast."
Coffee shop girl: "Large, right?"
Me: "Small."
