This article was written in order to bring up a balanced discussion about fraudulents complaints in the restaurant environment. This was because not the totally of products or services that are offered in the consumer s field by the companies reflect the real expectations that are put on them, or for this or that other product not really clarify the consumer s real needs, or even why the product or service not being considered good enough. This is how the opportunistic complaints take over some space on the discussion field, as far as the consumers can rely on law support where the consumers are always right way of thinking, those costumers uses their rights, or what they consider as being their rights, to support or create opportunistic complaints. However, this is what was intended to reveal on this research, the discrimination of when the costumer is registering a real dissatisfaction or just using the law as a way to protect himself and his interests seeking for some kind of benefit, especially on the restaurants.
