18. Long John Silvers
Despite its established fried fish fast food, Long John Silver’s seems to have gained a new reason for being praised: salty tasting foods! Besides, its customers are also salty owing to bad customer experience, dirty facilities, and long lines that take a lot of time. Apparently, there is a limited amount of time you can have before being stripped of the ‘Fast Food’ title.

One of the employees who worked at the fast-food chain argued that the joint has very greasy floors and that he was forced to buy new shoes every few months because of it. On average, only 41% of the interviewed individuals considered going back for a second meal. That is not nearly enough returning customers numbers. It seems like Long John Silvers need some polishing.
