If the big boss says that the food is too expensive to eat when ordering, you can answer it in the following ways:

1. Humor resolution: You can say, "It seems that our boss should find a rich friend to pay the bill!" This kind of answer can solve the embarrassment and has a sense of humor.

2. Ask for suggestions: You can ask, "Do you think it is necessary to change to something more affordable?" This will let the boss know that you care about his ideas and can also provide some solutions.

3. Discount discount method: You can offer your boss a discount or offer some discounts on your own initiative, which can meet your boss's needs and show your sincerity and concern.

no matter which way you take, you should be polite and professional to ensure a good customer relationship.
