Walking around the store no one seems to notice because the 12-pack fits so nicely in my hand. Too bad they don't make a family-pack.
However, I have to let go of the box at the counter, the look always goes from the box, to my hand, to my crotch, to my face and then their face usually turns red. Because of my height, my crotch is almost always above counter level.

PS. A few times, the person behind the counter gulped or swallowed, when looking. That always makes me laugh.
