I understand the code, but how can you argue against the exact wording of the code. Where is sign located? What does it say? How big is it? What do you consider "non contractual agreement? The list goes on. Clarity, man. Clarity!
The sign was located at the main entrance (which is the only entrance), and it is located in a place that is likely to come to the attention of the public. I humor you and say that the door IS the actual sign. the door is 10 feet tall, 4 feet wide. It is painted white and the text of the sign is written in 3 inch black lettering. To the left of the door is a button that a person must press to gain entry. One a person is inside, he immediately encounters a greeter who asks, " did you read the sign on the 10ft tall, 4ft wide white entrance door?" If the person says yes, they are allowed to pass.
The person entering the door has no stake in the property, and this is the first time he's been in the city, and seen the store.
That work?
