I think it's more that she wants them to realize some stuff on their own too rather than just do as told.
It's exactly like @Cynic and @Akashi-san mentioned. In a lot of scenarios like these, the establishment owner will clean up to impress, but as soon as the person who ordered them to do the upkeep is gone, they'll revert to their prior carelessness if they don't understand it for themselves.
I get she is helping them improve and stuff but doing it in such a drip drop manner is a little cruel I guess....But I guess it’s to do caution and other reasons
I guess next it’s about it not being fresh water and not having soap?
It’s a bit double standard though? I don’t think I seen her with head covers and some things when making her jam and the cooks in her home not much different? I am not completely sure tho, I get it’s a bit different since it’s not home but..idk
