If a customer asks, "Why is your photo so bad? The front is very clear, and the back is all empty! " ! "What should I do?

First of all, whether the foreground is sharp enough and whether the background is blurred enough is never a criterion for judging whether a photo is a "good photo", and it can't even constitute any judgment on photography skills or "common sense".

As one of the most basic and simple functions of photography, "recording" itself requires keeping "necessary" content in the image. So, whether the so-called "background" is "necessary content" is a question worthy of photographer's consideration.

The original question didn't specifically describe the shooting scene, the client's shooting intention and the theme of framing, so the above trade-off question can't be developed. But as a commercial photography project, I think it is very necessary to respect the customer's shooting needs and intentions. If the photographic environment is selected in a specific scene or place, besides the subject (probably people or things), the importance of the scene and place cannot be ignored.

Too vague background often leads to the effect of "lack of background"-this can be made up when the background is of little practical significance or the background quality is too poor. But I think, in most cases, this is just "making up". This kind of compensation can't replace a photo with perfect foreground and background, especially in today's digital photography and advanced technology, it will become easier and easier to replace an "artificial background" for a photo; Therefore, on the other hand, it is more and more valuable to feel the background with real experience and be truly recorded together with the background-and "presence" is also an important issue in photography aesthetics.

In addition, for commercial photography, although I don't have any practical experience personally, I think it is more friendly to customers to keep more "tolerance" and more options in the early shooting process. As @ Xia Xiaoyan said, under the same shooting, it is also a desirable means to shoot more "spare films" for the other party to choose according to the different choices of foreground and background. Commercial photography is more of a "communication" activity, and photography itself is an activity of considering trade-offs, so patient and full communication is very necessary.
