I went to a wallmart years ago here in michigan 1 time... I asked an afro-american girl where I could find something... she said, “i dont know” and never even looked at me. she had that little computer in her hand. I turned and walked out the door and have never been back in one since.
AT Publix, you get the opposite reaction. The employees will walk you to the right item. I have heard of employees stopping whatever they were doing to assist a shopper through the whole store.
