What Didn't Get Cleaned · CHEF! devlog

The staff still have to tidy up before the day's results appear, and the next day still waits for you to click Next day.
If something couldn't be done, the results now say so at the top: dirty tables, dirty plates, a messy bathroom or the trash, all still there in the morning.
That happens when nobody on your staff can do the job (with no busboy, nobody takes the trash out) or when closing up runs out of time.
The screenshot shows a day played without a busboy: the results warn that the trash is still there.
