== Food ==

It is often possible to retrieve used cups from the trash at fast food restaurants with "free refill" policies and refill them.

The United States has a culture of throwing many useful things and food in the trash. The advent of urban sprawl has the side-effect of creating many opportunities for dumpster diving in urban areas. Note, however that dumpster diving is in a similar sort of gray area as hitchhiking, with local legality depending on the particular state's laws, and the prevalent attitudes of local law enforcement officers.
