Which of the following adjustments would be made to a cover when a customer orders steak?

When a customer orders steak, one appropriate adjustment to the cover is to replace the table knife with a steak knife. A steak knife is specifically designed for cutting through the texture and tenderness of steak, usually featuring a sharper blade and, in some cases, serrated edges. This modification ensures that the customer has the proper utensil to enjoy their meal without struggle, enhancing their dining experience.

The other adjustments do not directly enhance the effectiveness of dining on steak. For instance, removing a dessert spoon may not be relevant because it is not typically used during the steak portion of the meal. Similarly, adding a soup spoon does not serve a purpose for a dish like steak. Lastly, adding additional forks would be unnecessary when the specific adjustment needed is to provide the appropriate knife for cutting the meat. Therefore, adjusting the knife to a steak knife is the most tailored and effective response when serving this particular dish.
