Ha! I'm still learning how to do the fast check out at the grocery store at Wal-Mart. I've got the Kroger one down pat. There is one Wal-Mart fast check out register that I try to avoid because I always need assistance with the crazy thing.
The other ones at this Wal-Mart haven't been a problem. Well, yesterday a really nice assistant explained what the problem was. We discussed the difference between Wal-Mart's and Kroger's. Even though she was about 30 years younger than me, she agreed when I said life was getting to complicated. So folks, no Ipad or Iphone for me.
