This man will defecate without washing his hands, and lie about it if you catch him emerging unwashed from the bathroom (besides their having been no sound of a sink running, he'll often leave the door open as he does his business). If asked to return to the bathroom and sanitize himself, he'll holler and curse and wish death upon me; and while he'll comply with the request at the time, he doesn't seem to develop a habit of washing his hands independently. What can I do to improve the situation?
I hope you get some suggestions. It's a tough one.
