That shit drives me crazy. If I didnt enjoy the flavor of the food, I just dont go again. If the quality was great, but the person wasnt, I wait a few weeks before trying agian to see if things change before denouncing a place. If the quality sucks, but the service is good, I do the same. The only time I badmouth something is whem both are terrible. Coming from a family of entrepreneurs, i know bad staff happens here and there, and they are usually dealt with withing a month or two. People like this are just miserable and hate themselves and look for any outside excuse to release their own self-hatred on others. Filthy swine.
