VIDEO: This woman who took loads of Halloween sweets is the internet's least favourite person right now

Just goes to show, you can't get away with anything these days. So don't be a jerk.

When this American couple knew they were going to be away for Halloween night, they decided to leave some boxes of chocolate bars on the porch for anyone trick-or-treating . Full-size ones, no less.

Oh, and they also made it into a social experiment. As you do.

He has a security camera set up out front and, when he got home, he reviewed the footage. They then uploaded the result to Youtube with the caption:

"Away from home, we left full-sized candy bars outside with a note, ‘Help yourself but be considerate!’."

He was pleasantly surprised by all the kids and teens considerately taking a few bars but leaving the rest for other trick-or-treaters - but one woman couldn't resist the bait and ended up taking the rest.

"We figured a group of kids would probably end up taking all of the candy at one point during the night, but everyone was really considerate…until this upstanding mother came to save the day.”

Oh, dear… take a look.

The video was at the top of the Reddit Videos page for the weekend and let's just say, commenters were less than complimentary towards the lady.

And let's not even mention the YouTube comments.
