There's a lesson in here for everyone: you shouldn't stare, you never know who has a hidden camera.
While you might suspect that the sneaky peekers in the video are all men, you might be surprised to find that this hidden camera experiment catches a whole range of people, young and old, trying to take a quick look at this woman's chest as she goes about her day to day business.
From ordering a coffee to hopping the train, there are plenty of people who can't help but ogle, and get stung rapid in the process.
The idea behind the stunt from Nestlé is to raise awareness of breast cancer with the Pink Ribbon initiative, and get people to #CheckYourSelfie, or check themselves by reminding women to examine themselves and ensure they're in good health. Obviously, judging by the video, enough people are taking a look, you probably should too.
