My perception is that 'Walmart' treats all there customers like thiefs. It is one thing to lock up electronics, but to lock up small ticket items is crazy.
I have to more or less ask permission to purchase razor blades from personal that need to be hunted down. New release movies(29$) are locked up, yet I can turn directly around and grab a season release that can cost 30$ and up. If you purchase an item that does not fit in a bag(cat litter dog food), a door greeter is supposed to scan you receipt. If this ever happens to me again, I will request the manager and in a very curt and concise way convey my annoyance.
If the Walmart corporation feels these steps are needed, then raise everything a dime in the stores and increase security. I also do not want to hear "Don't shop there if you don't like the way they run their stores." after Walmart has pretty much run most of the competition out of the area.
