Dinner guests + clearing up etiquette

[verybighouseinthecountry]

Another thread made me think about this. When I grew up, if you had dinner guests over you would never have let them help tidy up/clear away, and dishes were washed after they left (later on when we had a dishwasher it might have been loaded very quickly), not in front of them. Your job as the host was to feed/entertain them, not let them watch you clean up. It would have been very rude to let a guest help. Guests were close friends/family, not strangers or work colleagues.
I just read a thread complaining because the "guests never wash up" and it startled me a bit because I'd never offer because of the way I was brought up, it would be outrageous to think that a host would let me help, so it would cause offence to offer.
I'm wondering if this is just my family, or are other people like this?

Guests don't clean up afterwards their guests the host cleans up 😊

I would never expect guests to wash up.

But a family holiday or at a family house, I would expect to help or share the work.

Goodness no! If it's family then I ask for people to clear the table (usually the grandchildren) but otherwise either I or DH will clear the table while making coffee and the other one will stay with our guests. Washing up/stacking the dishwasher gets done after they leave, the only thing that doesn't get left until later is putting any food away.

If it's family I don't class them as guests. So if they want to help clear up then they can crack on.

Depends on the guests and the sort of party. A dinner party-with people I don’t necessarily know well-then no, no help expected or accepted. Friends round for dinner then yes, definitely expected and accepted.
