How can bussers and clerks under 18 handle alcohol for customers?

The correct answer reflects the regulations regarding the employment of minors in establishments that serve alcohol. Under certain legal frameworks, individuals under the age of 18 may be permitted to handle alcohol under specific circumstances. When option C states that handling is allowed after a sale is completed by an older cashier, it indicates that minors can participate in the process as long as they are not in violation of existing laws against serving alcohol directly to customers.

This regulation is often designed to ensure that while young workers can be involved in the workflow of a business, they are safeguarded against direct responsibilities that come with the sale or service of alcohol, which are typically reserved for those of legal drinking age. This allows businesses to maintain compliance with state laws while enabling young employees to work in various service capacities without engaging in prohibited activities directly.

In contrast, other options restrict the ability of youths to handle alcohol in ways that do not align with these laws, indicating that either total prohibition or excessive limitations would not be appropriate or consistent with the practices that allow minors to work in environments where alcohol is served.
