My love of my Southern people has me aching to tell you to stuff you appallingly horrid and insulting attitude you have towards people you seem to believe are inferior to you or that you think are just ignorant. My love of this forum and all the people who comment and give sound advice has me biting my tongue however and praying that either you didn't mean to be insulting or that you just didn't realize you were. I will say that most of your comments sound as though they are being spoken by a 13 year old child.
With all that said. If you are thinking about NC then you better stick to the large cities, Charlotte, Fayetteville, Raleigh, Durham, etc. However all of these large cities already have established real Greek restaurants. In Fayetteville we have a good size Greek Community. The places that do not have Greek restaurants will run you out of town if you come in with a bad -I am better than you, it is my way or no way- attitude. We just won't put up with it. I have noticed this cycle many times over the years when a new business opens and closes within a year. If you truly do want to establish a successful business anywhere in the USA I suggest you grow up a little in your attitudes and learn how to have a discussion with people without being insulting. One of the keys to mom and pop businesses are the owners personality.
I wish no ill will towards anyone so good luck on what ever you try.
