Iris,
I can say as a former employee, current customer and friend of the Murphy's that no other owner/operator does a better job at doing a great job with their restaurant. As Jenny said, Murphy works nearly night and day at his craft. He glady gives tours, samples and long stories about their place because he is truely involved and proud of the place. Infact, it is one of the very few places on 30A where the owner us involved with the preparation and serving of the good. The only other two I know for sure is Jeff at Bruno's and Paul at the Grayton General Store Deli. I know there are others but these are my favorites.
Back to the point. BF has a large and varied menu and had you asked, you would have been given samples of ANYTHING you wanted. It is true that they probably could have given you three separate flavored sliders but I think you would have been happier with the way they are normally prepared.
Bottom line, I think you allowed a little thing rob you of a great meal. Time and again, I have heard day that BF is some of the best BBQ they've ever eaten and quite a few of those people were BBQ restaurant owners in other cities.
I suggest you go back, decide which BBQ you want ( I suggest the brisket ) and enjoy a great meal. You won't be disappointed.
