The military commissary where I used to shop had a permanent sign mounted right above the grapes that said something like, "According to Regulation XYZ, consuming any amount of store merchandise before paying for it is shoplifting and is punishable by fines or jail time." 
Another store nearby had a sign on the cold beverage case saying about the same thing. Those military people don't mess around.
No one in my family eats or drinks in the store at all. I just can't bring myself to allow it, even if it's not a "per pound" item like produce.
