There is a well-known saying: "the customer is always right" I have never agreed with that saying, I consider that the client, from his position as a client, has a concept of what is the service or product he requires, but that idea is based on his expectation and demand, it does not necessarily conform to reality in all cases ... Now, it is true that the opinion of the client is very important ... but to what extent is it advisable to let the opinion of the client affect or determine the way in which we offer a product or service in our business?
