"It's so embarrassing actually," said Leota. "We went in to have dinner, we were under the impression Chuck-A-Rama was an all you can eat establishment."
If it's so embarrassing, why not just say, "Oh, I'm sorry," and not call more attention to yourself?
What confused the couple was the word "buffet," which they thought meant "all-you-can-eat buffet." If only people were more fastidious about avoiding redundancy, confusion like this wouldn't occur: you'd know that if there is an expression "all-you-can-eat buffet," "buffet" can't already mean "all-you-can-eat." This incident demonstrates the need for prescriptive grammar.
I love the name of the restaurant: Chuck-a-Rama. It sounds like a vomitorium.
UPDATE: Throwing Things notes that The Simpsons already did it. ("Mr. Simpson, this is the most blatant case of fraudulent advertising since my suit against the film, "The Never-Ending Story.")
