Very clever -- Daewoo Securities, as a charity event, sold bottles of dirty water out of a vending machine for KRW 1,000 (about a dollar). For each bottle sold, Daewoo will add KRW 9,000 and donate to UNICEF for cleaning drinking water. They are aiming to sell 5,000 bottles, which will amount to KRW 50 million in proceeds after making the addition. Daewoo said they will donate KRW 50 million (around $50,000) regardless of the result of the sales.
