Coffee trucks do not serve just coffee there is usually a menu of at least 3 or 4 options and they will serve HUNDREDS of people. ITZY members bought us coffee trucks for the 3 pre-recordings last week (Chae and Ryujin, then Lia and Yuna, and Yeji gave us egg tarts, because her coffee truck that she sent to MIDZY was from her brand sponsor Roger Vivier). So a coffee truck would cost thousands of US dollars, so it's a big prize. Add snacks to that and it's 50% more expensive than just a drink truck.
