When I saw them I wondered if Wal-Mart would pick up on the idea and fire their greeters. Why do I say this, because these feathered friends are friendlier than the greeters at my local Wal-Mart. The greeters there look like they've eaten a jar of sour pickles, they're mad as hell about it, and they're ready to take it out on you. I've yet to have one ask me if I needed a cart or say Welcome to Wal-Mart. They act like they're doing people a favor by letting them in the store to spend their own money.
There have been times when I've looked at a few of them, and said to myself I'm scared of you. I wanted to ask if they had woke up that way, if they were having a bad day or what, but I was actually afraid to say anything. So I just kept walking, and occasionally I would look back over my shoulder to make sure they weren't following me with an ax, lol.
Aside from the mean greeters, just trying to find a parking space at that store raised my blood pressure a few notches. By the time I reached the front door of that store I was usually frizzled. A warm welcome would have been nice.
