A Spock-like character always shows up in HN threads like these to claim perfect rationality, cite some figures, etc. You know what? People are emotional creatures. and sometimes, yes, a humiliating and excessive failure on the part of a restaurant is enough to warrant a strong and permanent reaction. This is a restaurant, after all. In the end, who gives a shit? You’re going there to have a good time. If you don’t have a good time, it’s perfectly valid to not go back.
We need to listen to our emotions more, not less in some circumstances. I don’t mean to make a scene, but to take it as a sign that we shouldn’t eat at that restaurant, take that job, date that person, patronize that airline, etc.
