Whoever said the "customer is always right" has never worked in customer service. Because those of us who have know that a customer's version of events can often stray so far from reality it's basically Sci Fi. This is why, when reading reviews for restaurants and hotels on sites like Yelp and TripAdvisor, it's important to check if the restaurant responded.
A screenshot of the review, and the response, was shared on the Reddit page "Murdered by Words." This is a flawless example of someone being verbally slaughtered.
They also claimed that they were "chastised" for eating the food after saying they weren't happy with it (seems fair?) and felt as if the staff "didn't care" and that the restaurant overall was "poorly managed and operated."
