Actually, unless you have caused a disturbance and they get a restraining order, they can`t ban you from any retail outlet that is open to the general public. Even though it`s private property, they open it to everyone for public use. So unless they`ve taken the steps of getting the court to songle you out, you`re still allowed to go as often as you like.Just never cause a disturbance. Keep your voice low, be polite, and behave professionaly. If someone does kick you out, just to piss them off,ask them for a job application. Legally they have to give one to anyone who asks or they`re in violation of Federal law.
