You are off duty at a popular local establishment in a relatively prosperous and secure neighborhood, but notice several things that bother you. first, this is the only building on the block with bars on the windows. second, you notice that female staff are being transported to and from work by managers who appear to be monitoring them closely. third, these women rarely converse with customers and seem nervous, looking around for their managers whenever interacting with customers. you get the strong impression they are being employed under coercive circumstances. what should you do?

Personally I would ask to speak with a manager and see what they would do, if they pointed me in the right direction I would talk with him and see if anything seemed odd. If I still got that feeling I would talk to the police about it and let them do the investigating.

I think the best thing to do is to report it to the police as suspicious activity. As a citizen you have the obligation to colaborate in the mainteneance of a healthy society in which everyone's rights are respected. It all indicates that these women rights have been denied. Police departments suggest to report any suspicious activity even if you are not sure, they will make an investigation and find out what is really going on. If nothing is out of the law then nothing bad will happen, if something is illegal there will be legal consequences.
