Which sandwich prompts the cashier to ask for a specified cooked temperature?

The Ribeye Sandwich prompts the cashier to ask for a specified cooked temperature because ribeye steak is a beef cut that can be served at various levels of doneness, such as rare, medium, or well done. Customers often have specific preferences for how they like their steak cooked, which directly affects the flavor, juiciness, and overall enjoyment of the sandwich.

In contrast, the other sandwiches listed typically do not require a specific cooking temperature. The BLT Sandwich and Grilled Cheese Sandwich are made with ingredients that are usually served at a standard temperature or cold (like bacon or cheese), while the Chicken Club Sandwich, though made with chicken, generally comes pre-cooked, negating the need for temperature specifications. This emphasis on cooking temperature for the Ribeye Sandwich is what makes it unique among the options provided.
