I think keeping your pants pulled up, just like no shirt, no shoes, no service should be enforced. Business's should enforce this. Some states have already implemented citations, laws, etc regarding this. Not only should it be for pants, but clothing all together. Women who feel they dont need to cover their breasts, Who wants to go into an eating facility and see someone in some form of undress? Who wants to be in the grocery store standing behind a person that you can see their bum, or pants down to their kneecaps? Who wants to be in a business and see a woman that has a shirt on that doesn't cover their breast. I think it should be a requirement just as no shoes , no shirt. I would rather see someones feet before I see their bum or boxer shorts. If they want to walk around with everything hanging out then do it outside of the business. Its a shame to even think you would have to tell someone how to dress, but its come to this.
