Went to Home Depot today. When I went to check out, I was directed to a checkout counter. To my surprise, it was a self checkout counter. You scan your own merchandise, tell the system you're done, press the credit card button, swipe your card, sign it, and walk out with your goods.
I don't know if this is a good idea or a bad one. I wonder how they prevent people from just dropping an item into a bag without scanning it? They probably have a video camera on each checkout counter.
The whole world is becoming self serve.
