I don't follow genius rule and am a mulit rule breaker at times. Have a few gray area hobbies ( women, gambling, substances,etc). Although never involved witl law and women more than a handful with gambling/the law. .as a general rule of thumb the law can not assume the patron knows establishment is illegal and as such patron gets id run through system and let go if clean. As for a John sting assume they have different approach as they are targeting us versus the provider.
