It seems like a pretty simple thing. When a humanitarian group hands out bags of food or sets up toilets for people who are poor or recovering from a crisis, the group puts its logo on the product.
It's a way of taking credit, which makes donors happy. It's a way of letting the recipients know where to complain if there's a problem. And if you're sitting at home and catch the logo on a TV report, you might be inspired to contribute to that particular charity.
But now, some people are questioning the branding of aid goods.
