Long John Silver's | Taco Bell

I felt like having fish last night. I hesitated to go to Long John Silvers on Dani Drive, because it has never been good . However, I did go there and ordered a fish and cole slaw meal. The fish was not hot and it was greasy. I went back inside the restaurant and told them about my meal. The man said it would take 3 minutes. I waited at least 10-15 minutes and went back up to the counter to ask about my order. The staff was very unprofessional, to say the least. I finally did get my fish, and it was surprisingly delicious and hot! My question is this: how can I be assured of consistent quality in the future? 1 star
