Final answer:
The provided information does not specifically identify which juice company was dissatisfied with Wal-Mart, but discusses market competition and Wal-Mart's impact on local economies. This impact may extend to various suppliers including potential juice companies.
Step-by-step explanation:
The question pertains to a situation where a juice company was dissatisfied with Wal-Mart, which was their biggest customer. However, the information provided does not specifically mention a juice company. Instead, it discusses the broader implications of market dynamics and competition, particularly in the context of the merger between Whole Foods Market and Wild Oats Market in the market defined as "premium natural and organic supermarket chains." The effects of Wal-Mart's business model on local economies are also mentioned, which could indicate dissatisfaction from local vendors or suppliers, which may include juice companies among others, due to Wal-Mart's competitive practices. It's important to note that while Wal-Mart's practices may have an impact on a breadth of businesses, without specific information about a particular juice company, we cannot confidently identify which juice company was dissatisfied.
The situation highlights the complexities of market competition and the impact that large retailers like Wal-Mart can have on smaller businesses. This could extend to a range of product suppliers, potentially including a juice company that found the consequences of doing business with a large-scale retailer to be challenging.
