1) I've lived in Washington State in four different towns, San Antonio, Texas and Connecticut. I was in the Army for 5 years and lived in Kansas, Missouri, Virginia, and South Carolina.
2) I've been to Alaska, California, Oregon, Arizona, New Mexico, Oklahoma, Colorado, Chicago, Louisiana, Alabama, Mississippi, Georgia, Florida, Detroit, Michigan, New York City....
3) I was simply talking about checkouts in Walmart and even stated that I was talking about a local Walmart in my local town where I live with 25,000 people. So no need to lecture me about how it's only a small sample and how I could learn from others with more experience. I am well aware that I haven't experience Walmarts from all over the country.
