When there is an occasion, I used to serve soda in individual bottles (sometimes in individual cans). But we noticed that the soda were mostly half-empty which means the guests couldn’t drink it all. What a big waste especially when there are lots of children with the guests, you can imagine the leftover. But now what we serve is soda in big bottle with matching drinking cups and ice cubes. That way, a heavy drinker can get a second helping while a light drinker can most likely finish one small cup of soda. Wastage is at least minimized.
