Why did the supervisor decide to stop giving away coffee cups?

The supervisor's decision to stop giving away coffee cups stems from the assessment that this practice did not yield sufficient return on investment in terms of new or repeat business. Businesses often utilize promotional items like coffee cups to increase brand visibility and attract customers; however, if the strategy fails to translate into tangible business growth or increased sales, it becomes impractical. In this case, the lack of measurable benefits from giving away the cups indicates that the costs associated with providing them were not justified by the results, leading to the conclusion that the practice was not beneficial for the company.

The other choices do not effectively capture the rationale for stopping the distribution of the cups. While the cups may not be standard products sold by the company, or could be deemed expensive, these points do not directly address the connection between the giveaway and business outcomes. Similarly, the notion that too many cups were distributed lacks the context of financial evaluation and the overall impact on business strategy, which is central to the supervisor's decision.
