贾乃亮和娇兰，遇到了一场狼人杀

Core Viewpoint - The article discusses the complexities and potential issues surrounding the authenticity of products in the cosmetics industry, using a scenario reminiscent of a "Werewolf" game to analyze the roles involved in a product's supply chain and their respective levels of suspicion [4][12]. Role Analysis - Role 1: The Streamer The streamer has no suspicion as they did not handle the product directly, which provides them with a solid alibi [4][6]. - Role 2: The Official Flagship Store The flagship store theoretically has some suspicion, but the likelihood is low since they are the manufacturers of the product. The cost of producing counterfeit goods would outweigh the benefits [4][6]. - Role 3: The Warehouse The warehouse has significant suspicion due to the potential for employees to substitute genuine products with counterfeit ones during the packing process. Such behavior is not uncommon in warehouse operations [6][7]. - Role 4: The Courier The courier has some suspicion, but it is limited. The likelihood of tampering is lower for non-high-value items like cosmetics compared to electronics or luxury goods [8][9]. - Role 5: The Consumer Consumers have some suspicion, but it is also limited. The brand's refusal to accept consumer-submitted tests is reasonable, as there is no way to verify the authenticity of the product brought in by the consumer [9][10]. - Role 6: Other Consumers Returning Products There is a clear suspicion regarding other consumers who may have swapped genuine products with counterfeit ones during the return process. This scenario highlights a systemic issue rather than individual wrongdoing [11][12].
