Hy-Vee grocery stores here in Kansas keep a small refrigirator up front stocked with milk just like you see soft drink machines in most stores. Also, I submit to you that you'd have to pay more for your milk if Wal-Mart hired people with IQ's above 85. You should have just set your milk down right there and left after about four minutes of waiting. Why should they give you good customer service if you'll keep buying from them regardless of how they treat you?
