i just provide plain bread (with jam or butter or peanut butter) and biscuits ($10/pack), no drinks. my maids drink a lot of coffee and ovaltine everyday (3 cups). each big can of ovaltine costs nearly $70, 1 maid can finish it within 3 wks. I don't want to pay her over $200/mth just on breakfast (if incl drinks).
sometimes i will give them canned or boxed drinks (e.g. lemon tea and vitasoy) if I bought 6-12 packs.
you shd just tell your maid NO DRINKS WILL BE PROVIDED WITH IMMEDIATE EFFECT!
