Which of the following is considered a breach of customer rights?

A breach of customer rights occurs when actions or policies undermine the principles of fair treatment and equality. Denying service based on race or gender directly violates these principles, as it leads to discrimination and exclusion based on inherent characteristics that individuals cannot change. This type of behavior not only undermines the values of equity and respect but is also illegal in many jurisdictions, reflecting the recognition that all customers have the right to be treated equally and without prejudice.

In contrast, insisting on valid ID for alcohol purchases is a standard practice designed to uphold legal regulations related to age verification, which does not infringe on customer rights. Offering discounts on certain days is a common marketing strategy aimed at attracting customers and does not discriminate against anyone. Similarly, implementing a loyalty reward program is intended to reward customer loyalty and can be beneficial for both the business and its customers, promoting positive engagement without breaching rights. Therefore, the denial of service based on race or gender is the clear infringement on customer rights.
