It depends how long they're staying and how frequently they come round. If they're staying for several days, I don't expect them to at least work out how to use the kettle themselves. I'd also expect them to bring a bit of their own food if they're staying for longer than a week - especially since they're frequently just staying with us because of our location, not because they like us so very much.
Booze - well, they're welcome to some of mine, as long as they don't take the piss.
Friends who visit a couple of times a week or more don't get treated like guests, but members of the household.
I also expect them to be nice to my daughter. One guest is uninvited because he wouldn't even acknowledge her existence. I don't mean playing with her non-stop, but saying hello and so on, just like they would to anyone else in the house.
