Final answer:
It is important to refuse to provide any unofficial incentives such as merienda to the staff member and to report the incident to appropriate authorities. Engaging in any form of corruption is both unethical and illegal, and the application should be processed based on merit and proper procedures.
Step-by-step explanation:
The scenario presented involves a request for an improper advantage, essentially falling under the realm of corruption. In situations like these, the proper course of action is to refuse to provide any unofficial incentives or merienda to the staff member. Instead, you should report the incident to higher authorities within the city hall or an anti-corruption agency. Offering a bribe, even in the form of a snack, can perpetuate a system of corruption and ultimately is against the law.
One should maintain integrity and refuse to participate in such practices. The correct response would involve a polite rejection of the staff member's hint and perhaps a suggestion that the application process should be completed based on its own merit and the proper procedures. If the staff member insists, it would be wise to seek assistance from another official or a supervisor.
Remember, engaging in corruption, no matter how small it might seem, contributes to a larger problem and is not a responsible or ethical way to handle the situation.
