Are you bringing back less than you went out with

Are you bringing back less than you went out with
 

situation:

My brother went out an hour ago, I not remembering to look at what he went out with. Now he has come back, and can I ask him?:

-Are you bringing back less than you went out with?

Because usually my brother goes out with a backpack, so I fear he may have left it where he has just visited when I see that he is not wearing his backpack.

You can use this.

This term is often used in gambling.

You do well if you come back with more than you left with.

Thank you~
