Five Man Failure:Small business with less than 10 people. The business is usually dysfunctional. The CEO of the company has 'observation blindness' and coddles bad employees. In a large company issue employees would have been sacked for more dynamic candidates.
That tube store employee is passive aggressive and never emailed me to tell me that my special order was cancelled two months ago. They're running a "Five Man Failure".
