Final answer:
Rukmani dislikes selling vegetables to Biswas because Biswas is dishonest, manipulating payments or situations to his benefit, making the selling experience unpleasant and unfair.
Step-by-step explanation:
Rukmani dislikes selling vegetables to Biswas because Biswas is dishonest. Biswas's character often engages in deceitful practices, providing insufficient payment or manipulating the truth to his advantage. This behavior affects the sellers, including Rukmani, making the interaction unpleasant and economically distressing. In the context of the story, characters that embody dishonest traits, like Biswas, serve as obstacles for the protagonist, highlighting the struggles faced by individuals like Rukmani within their community and the broader socio-economic environment.
Dealing with dishonest individuals in market transactions is an unpleasant experience, as it undermines trust and fairness—core aspects of any economic interaction. Rukmani's dislike towards selling vegetables to Biswas emphasizes the importance of ethical conduct in trade, and the impact unscrupulous individuals can have on the daily lives and livelihoods of others. The aversion characters like Rukmani feel towards interacting with such individuals is reflected in real-world scenarios where sellers prefer dealing with honest and respectful customers.
