One last comment... the argument seems to be that these places only have to follow the laws of the state in which they are licensed.
An analogy, if you will, on a totally different topic:
Illinois allows its citizens to own guns, but you cannot carry them around with you; we have no right-to-carry laws. Indiana, our next door neighbor, has right-to-carry laws, meaning its citzens are allowed to own guns and carry concealed weapons on them. Now, if a person who lives in Indiana has a gun in their pocket, and they drive across the border to Illinois where that is illegal, and a cop pulls them over and finds they are illegally carrying a concealed weapon... do you think the argument that they were operating under Indiana law will hold up in an Illinois court? NO, because when you are in our state, you need to follow our rules.
