Is it permissible for a husband to bring bread or other food from a restaurant where it is forbidden to take it out, under the pretext that it will be thrown away?

This husband is a private employee in a restaurant, and he is not allowed to take anything from it except with the permission of its owners. This is because his disposal of anything without permission is considered treachery and an impermissible transgression. However, there is no sin upon him if the restaurant owners throw away bread or food, or abandon it, for him to take it and benefit from it.
