Hawaii - Kahala Mall

After bathing in the sea at Waikiki beach, we had shopping time at Kahala Mall not Ala Moana Center where we often popped in last time. 
There are many nice shops such as Whole Foods Market in the mall.  I just wondered that why vegetables  are piled up on a shelf at Whole Foods Market.  Looks good and a cool shot, but lower vegetables must be pushed and go off.
