Social service
Social services are sort of Charitable contributions done by some companies to some communities. Social services are external to their business and the companies do not get any financial compensation for the services provided. This is a good way of doing PR and getting positive press coverage. There is the hazard of Social Greenwash wherein a company tries to hide it's bad sides by making voluntary contributions and making a lot of noise about them.
Example:
Some Jordanian merchants donated 40 truckloads of food and other supplies to Iraq after the war, which could be used as a reason for endorsement of the companies responsible
