The girl did not clean the kitchen floor properly. This is the duty of the girl in the house. she was reminded. Still it was not cleaned properly. her Owner was not pleased. Now she drinks her wine from the floor. The kitchen floor shall be clean. The girl shall know, she shall keep it clean at all times. If not, the expensive wine may get a sour taste. If clean, it still tastes good. Important difference. Especially for the slavegirl doing the drinking.
