about 2/3 of those "rules" I agree with
some other ones that might be applicable. Be on time, but don't be early. If you can't make it for whatever reason then have the decency to let them know as early as possible. Be clean. Be sober ( or mostly sober). Respect the place you are visiting, even if they don't always. Brush your damn teeth. Leave when you're expected to, and the lady will generally let you know, in a graceful way, when that is, if you haven't already picked up to go yourself. She will choose if she is going to spend extra time with you or not. Likewise if she isn't clear that the extra time requires an extra financial consideration then that's her fault not yours. We're all presumably humans with human emotions, and sometimes we'll just hang out with each other because we want to. Take your shoes off at the door unless she tells you otherwise. Smoke only if she says it's ok.
of course, there's a zillion others under "common sense and courtesy" , but it always amazes me how ignorant some people can be. many of these types of things apply to SPs just as much as they do to their clients.
