Really poor children in really poor neighborhoods have no habits of working and have nobody around them who works. So they literally have no habit of showing up on Monday. They have no habit of staying all day. They have no habit of 'I do this and you give me cash' unless it's illegal.
One of the key things is to encourage people to have a go in the kitchen and not to be embarrassed by it. Try and spend a couple of nights a week cooking something up. It doesn't have to be complicated, it can be something really simple.
