I thought it an interesting article. I noted that Tescos keeps their bins locked while others throw bleach onto their bins. How churlish is that? "if we can't make a profit, then no one will get a break?" 
And wasteful, and damaging to the environment - more bleach out there, and damaging to any animal or wildlife foraging in the area.
Hate Tesco.
Oh, it wasn't fear that put me off dumpster diving with them, I just never seemed to be able to coordinate it.
I'd happily go into a dumpster, however. Wouldn't bother me a bit.
I mean, I've eaten plenty of food out of them, why not?
FWIW, I knew many people who ate entirely this way - they never purchased things from shops.
Most were not meat-eaters, so there's no real harm in it.
Especially in Boulder, where most of the poachers were staff, anyhow.
