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

The advent of urban sprawl, and the The United States' culture of throwing many useful things and food in the trash has the side-effect of creating many opportunities for dumpster diving in urban areas. Port cities are especially good. 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.

Grocery stores are prime targets for food ([[:trash:Trader Joe's|Trader Joe's]] is really wasteful and has lots of organics). Grocery stores cannot sell packaged foods past their expiration date, and so throw them away in dumpsters behind the store.
