For a chicken salad on croissant, what is the appropriate action regarding cheese?

Adding cheese to a chicken salad on a croissant should be done only if requested by the customer. This approach honors customer preferences and dietary choices, allowing individuals who enjoy cheese to have it included while respecting those who do not want it. Customers may have varying tastes or dietary restrictions that influence their decision on whether or not to add cheese, making it essential to accommodate those preferences.

The other options suggest a more one-size-fits-all approach, which does not align with providing personalized customer service. Always adding cheese or never adding it fails to consider the varied preferences of customers and restricts their choice. The notion of only adding cheese on weekends introduces unnecessary restrictions that do not align with standard practices for accommodating individual customer requests at a food service establishment.
