Is It Cool To Eat Stranger's Leftovers At Restaurant?

Ever walked past a table at a restaurant where the people just left and debated whether to grab a handful of the fries they barely even touched?

There's a debate online right now about whether or not it's cool to eat a stranger's leftovers off a table at a restaurant. There's even a term for that: "Free-range mooching."

The big pros: Free food...you cut down on the insane amount of food waste at restaurants...and it's not as gross as, say, eating food out of a dumpster.

The big cons: You have to tuck ALL your germophobe tendencies away...it's not socially acceptable and it could be embarrassing if people see you...and since it could be a liability issue for restaurants, they could kick you out if they catch you.

So after all that...would you do some free-range mooching? And if the answer is yes, are there some foods where you'd draw the line, like soup or half a milkshake?
