It depends.. If I know the guests very well, then I’m sure they know me well enough to know how I want it done, so I’d force them to get off their asses and help me. On the other hand, if I don’t know the guests very well, I’d find it rude if they don’t offer their help. But if they do offer their help, I’d still deny it because I’d prefer to have it done my way, although it was a nice gesture. Added to the fact that they didn’t expect to come to my house and help me clean up. So what I basically expect is manners from the guests rather than actually wanting help. Although it’s useful if needed.
