Shopper #1 happily shopping and filling her cart. Shopper #2 comes along while #1 is looking at another item and reaches into #1's cart takes out a box of rice and puts it into her cart. #1 sees this and says, Hey, that's my cart you're taking my groceries, #2 says there are more boxes of rice down the isle to the right, and walks on.
Also I heard it said 2 times to other shoppers. "Why can't you locals shop during the week?" Well guess what? We locals work all week and can't get to the store on a weekday. We also have to pay the high price of living out here. Many locals have 2 & 3 jobs.
