Months ago, a Walmart employee demanded I show a receipt for my purchases. Today, a Walmart employee demanded to see my brother's receipt. The employee was rude, surly, and demanding.
The employee at Walmart is a random person; sure, he can ask to see what's in my pocket, but that doesn't mean I just have to empty my pockets for this person because he says so.
Apparently Walmart in Sauk Centre assumes its customers are thieves, and rudely, impolitely demands that customers prove they are not.
