2. Article 53 of the Law on the Protection of Consumer Rights and Interests stipulates that if a business operator provides goods or services in advance, it shall provide complete products as agreed. If it is not provided in accordance with the agreement, it shall fulfill the agreement or return the advance payment according to the requirements of consumers. It is a breach of contract for the cinema to delete eggs or not fully show films, and it should fulfill the agreement or return the advance payment according to the requirements of consumers.
Therefore, you have every right to ask the cinema to put eggs. If the theater doesn't put eggs, collect the evidence that the movie has eggs but the theater doesn't put them, complain to 123 15, or directly file a lawsuit for compensation.
