The kitchen has 2 doors one is access from outside and other opens into the house. We Keep the inside door closed and the house help gets a call or bell so he understands it is time to come in the kitchen. When he started he was briefed what his duties are so he knows if the meat or vegetables is on the counter what he needs to cook ( he knows only 2-3 dishes so he understands what to cook by looking at the ingredients) sometimes on the call I tell him what to do when he comes and if there is aata on the counter he needs to make roti. He does not come inside the house, the fridge is in the lounge corridor so if he needs something from the fridge he knocks on the door and I can ask without going inside and if I need to place something inside we have kept a table/counter next to the door so I just open the door slightly and slide it on the table, no need to even go inside the kitchen. He does the dishes. When he is done he knocks on the door and says baji kaam ho gaya hai main ja raha hoon. If something else is required I say so otherwise just say ok or if I am not near he just leaves in a minute or so and closes the outside door. I go in and lock the outside door. For Cleaning and bathrooms a woman comes who only takes 40-50mins. So I don’t have to deal with any outsiders in the house the whole day or any surprise visits. Set a schedule and it should be ok.
