Since as the law is written in plain english makes no mention of signage, I would like to see a cite...
Case law. Signs constitute legal notice of a store-owner's intent. Same goes for "No shoes, no service" signs in restaurants.
...that shows CT used for ignoring a sign or other non verbal "rule".
Newsflash: A sign is "verbal." Anything written or spoken using a language is "verbal." When something is only spoken, that puts it into a subcategory of verbal, commonly referred to as "oral."
Why do other states give signs legal weight if their already existent trespass statute would suffice? Why in GA where we have similar trespass laws is this not an issue?
Haven't a clue. This is the Colorado subsection, not the Georgia subsection.
If I walk into McDonald's without a shirt on or take my shirt off once I am inside (say my 8 year old spills his orange soda all over me). Am I then in violation of the LAW if they have a sign that says "shirt and shoes required"?
Yes, you are. At least here in Colorado. However, if you actually spilled something on your shirt, I'm reasonable sure the proprietor would allow you to remain inside, albeit in the bathroom, while you remove your shirt and rinse out the orange soda.
How about if I am wearing a jacket with no shirt on under it?
That would meet the intent of the law, which is to prevent bare-chested people from parading around the restaurant.
What happens if I take my shoe off at the table to get a rock out of it? How is any of this different?
That, too, meets the spirit of the law, for as soon as you remove the rock, you'd undoubtedly put it back on your foot. Even if you didn't, so long as you were seated at your table, I seriously doubt they'd throw you out, as their primary intent is to prevent people from walking in and around their establishment while barefooted.
ETA: How about you walk into a business and the manager says "we don't allow weapons in here." You ask him if he is asking you to leave and he says "no, have a good day." Have you violated the law if you continue shopping?
If you continue shopping with your weapon on your person, then yes, you are most certainly breaking the law. If you store it in your vehicle before continuing your shopping, then no, you are not breaking the law.
Remember laws only make things unlawful
You're 100% correct! And
it's those laws, specifically the Colorado Revised Statutes, which
make both give proprietors legal authority to establish and post some requirements for entry/presence on their premises. They also make it illegal for patrons to behave in the ways you're suggesting, dis-respective of the proprietor's spoken (oral) or written (signage) intent.
There is no penalty for ignoring a sign in CO, so it MUST be legal.
Keep doing that and let me know how that turns out.
Over the last two years, at least one door-to-door salesman was arrested in our apartment complex for trespassing. They have no legal recourse as there's a small placard which states "No Solicitation on These Premises" on the door to the apartment complex office. From what I understand, however, the management company refused to press charges. Their main intent was to send a clear message to the solicitor's parent company that door-to-door sales won't be tolerated.
Nothing in that makes carrying a weapon concealed unlawful.
Keep pushing that button, as well. I'd like to say "let me know how that turns out, too," but from what I understand, they don't give prisoners access to the Internet.
