What action might a guest needing special attention take to get your attention?

A guest needing special attention is likely to utilize more visible and direct methods to catch the attention of a carhop, especially in a bustling environment. Honking the car horn, flashing headlights, waving, or using hand signals are all actions that generate immediate visibility and urgency. These methods are designed to communicate clearly in a setting where verbal communication may not be possible, allowing the guest to quickly convey that they require assistance or have a specific request.

In contrast, watching for a signal is more passive and relies on the carhop's actions rather than the guest's initiative. Changing an order does not inherently signal a need for special attention; it may just be a routine request. Requesting to speak to a manager implies a more formal complaint or issue, which might not be the best course of action for an immediate need that could be addressed by the carhop directly. Using direct and obvious signals to attract attention is generally more effective in a fast-paced environment like that of a carhop service.
