Evaluation by the worst!

For many years I read and hear about what constitutes a brand and determines its value. There are plenty of different opinions and each wants to emphasize a different aspect. I think that is constantly ignored the negative phenomena that participate in the evaluation of a brand. Any judgment about a brand is based on personal experience with that brand. It is easy to forget what it was good for a number of times, and after the first negative experience - brand is past! There is a saying that the reputation is long building process, and disappear in no time. So it is with the brand. For example, for years You can go into a bakery, but when first time they give You something of poor quality, You are going to leave them. Years can pour gasoline on a pump, but after the first unkind services You will forget them forever. You can go for years at a coffee shop, but after the first 'mischief', you will never go there .... All this is happening because: 1. We live in a time of overcrowding products and services, and we are not forced to suffer something bad for ourselves, but the next moment we turn to next alternative. 2. Professionalism is understood and mandatory. 3. Superior service is meant. 4. Top quality is understood. When taking into account all ,the above mentioned, components, leads to the conclusion: Brand strength is measured by the strength of the weakest link in the marketing mix!
