Is it permissible for common people and expatriates to eat from the food placed in refrigerators on the road as charity, even if they are well-off and employed?

It is permissible to eat from the food placed in public charity refrigerators, even for those who are not in need, because the objective is to preserve blessings or to give absolute charity. An exception to this is if the food is designated for a specific group, either by explicit notification or common practice, in which case it is not permissible for others to take from it. If the food is scarce, it is preferable for the wealthy to leave it for those in need.
