You got some good exercise today. And yea, don´t forget you need to et some groceries

Today, I walked 2 miles to the store, filled my cart with groceries, and got to the cashier only to find I had forgotten my wallet. I tried to explain but got the nastiest stank-eye from the cashier, the manager and everyone in line behind me. I walked 2 miles home, hungry and embarrassed. FML
