My parents are (well, were, then they got too old) dumpster divers. They live in a university town and at the end of the year the students all throw away lots of stuff. Some of it's a good haul- just pick up a box of jars of olives- and other times it's crap. My parents often try to keep the perishable stuff which often is clearly past its prime, and I have to go through and organize what is close to a hoarder's paradise in the basement on a regular basis.
I have mixed feelings- obviously they're identifying stuff that would just be waste, but it frequently ends up just sitting around forever because who needs a case of olive oil when you're 75? There is also an entire closet which is filled with hydroflasks. Often the whole area smells like beer, because they collect lots of cans (I used to give them a hard time about this but they were making a few thousand dollars a year...)
