No it isn't!
Gross I mean, not if the bags are sealed. Indeed, here in the UK, supermarkets are now wise to the ways of "freegans" IE folk that dive the skips at the back of the supermarkets in search of free nosebag. Now most of 'em lock the skips, leaving perfectly edible food to rot in there. There are people starving in the world FFS....

Exactly
If they're throwing it out due to legal issues (can't give it to local poor houses for fear of illness, etc.), why shouldn't those less fortunate retrieve it for themselves? Last month I couldn't even pay all the rent, much less purchase food, and those potatoes kept us full of warm, fresh food for a good while.

Bolt Cutters...
Some restaurants where I live do this - but they only use padlocks on chains. I've been tempted to use a good pair of bolt cutters, or a hacksaw, or a crowbar, just to prove a point, and have their secret special foods away.
Barstuds.
