Is this mess normal?

Apologies for the boring subject matter. Bedroom replastered after renovations. Concrete floor. Plasterer has left hundreds of plaster drips over the floor, some of which are slightly raised. Floor will be carpeted eventually.

I would like to know whether this kind of mess is standard or whether the plasterer was trying to cut corners as he knew it wasn't a finished floor. Happy with the plaster job, but peeved that I'm now left with a mucky floor, even if it is being covered.

Quote included "sheet up appropriately" as part of the service.
