Yup, just like that.
The rubbish that was strewn over the floor, dur to the complete failure of any of you to organise a rota, as you have no leader, is all gone.
The dirt and damp atsratung to encroach in along the walls has been cleaned.
All the stuff that was carelessly left blocking doorwarys or people's way through places has been moved back to sensible positions.
It looks as if someone has even replaced all the plants that died when various people forgot to water them.
... unusual. You cannot pretend to have heard of the team of people who break into secure installations and re-decorate. Maybe they've left a bill?
