Why did a supervisor decide to stop giving coffee cups to customers?

The supervisor's decision to stop giving away coffee cups is rooted in the evaluation of the effectiveness of this practice in generating new business. By determining that the cups did not attract enough new customers or increase sales adequately, the supervisor is focusing on the company's bottom line and overall business strategy.

In many business environments, every promotional tactic should ideally contribute to customer acquisition or retention; if this strategy does not yield a satisfactory return on investment regarding new business, then it makes sense to reassess and modify such practices. The choice reflects a common operational decision-making process where resources are allocated based on their effectiveness and contribution to the organization's goals.

While other options may provide different viewpoints, they do not align with the context of assessing the business impact of the giveaway. The options mentioning the cost of the cups or their typicality as products sold by the company address other aspects of operational decisions but do not directly tie back to the primary concern of attracting new business.
