Would you ever consider Dumpster Diving?

From Wiki: “Dumpster diving (known as skipping in the UK) is the practice of sifting through commercial or residential trash to find items that have been discarded by their owners, but which may be useful to the dumpster diver.”

What are your opinions on this? Would you or have you ever done it? Where would you draw the line? Would you eat discarded food or only take non-edible items?

As someone who has gone dumpster diving, I’m wondering what others think of this practice and of those who do it.
