It's Never The One In Front

Well the fresher food is towards the back that's why I do this.

The one in the front is the one they need to sell first.
When buying perishables, always go to the back. (Especially milk.)

"Everybody has already looked at this bottle of pepsi!"

Gotta get a pristine one

I do that when I'm buying cosmetics or deodorants, cause I feel like the first ones are often being tested.
