I also would like to share the food at home with the maid. But my experience was bad.
e.g. I bought a big pack of biscuit for the maid. She ate them all within two days
I bought coffee for her, she drank 3-4 cups of coffe a day.
I let her take the dishes she liked for meal and she controlled the portion herself. However, she picked the whole part of fish w/o bones but left the remaining part totally w/ bones for my husband
You let her eat organges. She ate 3 oranges a day....etc
All these showed they didn't have self-control ability coz that didn't cost them any money. However, if she bought biscuits and coffee herself, she would eat normally.
So now I was trained not to share the snacks w/ the maid and I prepare the meal portion for the maid.
Do your helpers have self-control when you share snacks w/ them?
