Once after a long pax trip on a VC10 to Washington, self and team were (despite the efforts of InFlight Catering!) starving, so having picked up hire car we stopped at the first fast food - Wendy's IIRC - for a massive order.
Order acknowledged then: "EE dinner Go" from the burger flipper.
After much repeating and speaking slowly, we discovered it was a question, asking if we wished to partake of the culinary delights on the premises, or have it as a takeaway.
Got it yet? "Eat in or go?"
