Wanna do Lunch?

One of the recurring themes of this blog relates to ongoing changes in the English language. Words change in meaning over time.

I have noticed that folks who work in stores (grocery, shoe, whatever) refer to their meal-break as "lunch," regardless of the time of day. So a cashier at a supermarket would say, at 2:00AM, "I'm going to take my lunch in a half hour."

Will lunch cease to mean the midday meal? Stay tuned for the next 50 or so years and we will see.
