The sign to your left above the snacks commands that you "grab something good" and who are you to disagree?
You reach out and grab the goodest thing you can see in your immediate area.
The young woman in front of you with the nice butt disagrees firmly with your liberal (and erroneous) interpretation of the sign.
In a feeble defense against her disgusted glare, you point at the sign.
She nods and grabs something herself. You scream as she squeezes.
