Only a little more off-topic, but not too far considering where this is heading...
I had to return some items to CompUSA the other day and the manually entered stuff into their register and after messing up (and me pointing this out) had to do it again. I think my credit card finally ended up correct. I did bring up the fact that at HD the return procedure is much easier with the bar-codes and all. They just looked at me.
I did mention to them that it was amazing that a home store had better automation than a computer store. :-) (Maybe it's because they need it more?)
