Paint on bare plaster

[Toughie]

Hi,

We recently had our bedroom painted and it seems our decorator used our bare plaster in the hallway to “roll out” the excess paint on his roller.

This was final coat paint and not watered down for a mist coat.

Do I need to scrape this off before a mist cost is applied? It has been done on multiple walls

Thanks

No id leave it.
Not good practice to do that but I know decorators that don't worry about mistcoat.
On goes the paint as is.
