I am writing a scene that takes place during a fancy corporate party, and I realized I don't know why these parties happen. The party is being thrown by three growers associations. Representatives of big corporations involved in agriculture and related industries are there. There are also a few individuals from more indirectly related industries, like Nestle Waters. I won't be spending a lot of time explaining what this party or the businesses involved are all about in the novel, but I do need to understand, at least for myself, why they are there.
Many thanks in advance.
