Letícia Mattos, a 37-year-old advertiser, hoped to end the day with a tasty snack when placing an order via iFood at the McDonald’s on Rua Voluntários da Pátria, in Botafogo, Rio de Janeiro, on the night of July 24, 2025. The order, a promotional combo with two sandwiches, fries and Coca-Cola Zero, arrived around 9:30 pm. Upon opening the package, Letícia noticed that one of the sandwiches, a Cheddar McMelt, did not contain the burger, just bread, sauce and toppings. The initial surprise gave way to indignation when, when reporting the problem through the app, the store’s response was a dry “impossible”. After insisting, Letícia was promised a new snack, which never arrived, even after three hours of waiting. The lack of a solution and an apology led the customer to consider legal action against the fast food chain.

The delay in a solution, combined with the lack of an apology, led Letícia to consider legal measures against the network.

McDonald’s Response
McDonald’s issued an official note in response to the case, refrking that customer experience is a priority. The company acknowledged that the interaction reported by Letícia is not in line with its service standards. The network stated that it was in contact with the customer to resolve the problem, but did not detail the measures that will be taken.

Context of fast food failures
Errors in fast food orders are nothing new, but Letícia’s case highlights the importance of efficient service. In 2024, Reclame Aqui registered thousands of complaints against fast food chains in Brazil, including problems with incorrect orders, delays and inadequate service. In the case of McDonald’s, incidents such as cold meals, exchanged or incomplete orders frequently appear on complaint platforms.
The Botafogo unit, where the incident occurred, has already been mentioned in other complaints for similar problems. The pressure forSpeedy service can lead to order preparation failures, especially at peak times. The “impossible” response given to the client suggests a failure in internal communication and team training.

- Problems with incorrect orders represent 30% of complaints.
- The Botafogo unit has already faced criticism for delays and errors.
- Inadequate training can contribute to service failures.
This data reinforces the need for improvements in the internal processes of fast food chains.

Consumer expectations
Fast food consumers value speed, quality and respectful service. Cases like Letícia’s show how failure to meet these expectations can generate dissatisfaction and damage the brand’s image. The popularization of delivery apps, such as iFood, increased the demand for efficiency, but also exposed weaknesses in the customer service system.
Letícia’s experience reflectsThere is a bigger problem: the lack of agility in resolving errors. Consumers not only expect a correct product, but also a quick and empathetic response when something goes wrong. The absence of an apology in Letícia’s case intensified the perception of neglect.
- Speed delivery is the main expectation of 70% of fast food customers.
- 60% of consumers abandon brands after negative experiences.
- Delivery orders represent 40% of McDonald’s sales in Brazil.

Legal implications
Letícia Mattos informed that she intends to take legal action against McDonald’s, a decision that reflects the emotional and financial impact of the experience. In Brazil, the Consumer Protection Code (CDC) protects customers in cases of service or product failures. The delivery of a sandwich without a hamburger may be classified as a quality defect, entitling you to a product replacement or refund.
In addition, the store’s inadequate response and lack of solution may constitute non-compliance with the offer, another point provided for in the CDC. Lawyers specializing in consumer law suggest that cases like this can result in compensation for moral damages, especially when there is obvious disrespect.
- CDC guarantees replacement or refund in cases of quality defects.
- Inadequate responses may be considered disrespectful to the consumer.
- Compensation for moral damages ranges from R$2,000 to R$10,000 in similar cases.
- Actions against fast food chains have grown 20% in the last five years.
