It seems as though many shoppers have found that Walmart has begun locking up products which cost less than ten dollars, forcing customers to find an employee with a key. Finding someone to unlock a case really difficult most days and many have begun going other places for those products. Often the most locked up things are in the beauty department. Things like mascara, other makeup items and even shampoo and pregnancy tests. One store even locked up underwear.
Target is doing this as well as other stores. Places like Macy's and Dillards have long had cosmetic and beauty products manned by a worker behind a counter.
I can see how this would be frustrating, it's rarely easy to find an employee to help or even answer a question. I also understand that things like makeup are probably frequently shop-lifted, they are usually small items easily tucked into a pocket of bag. Other stores have had certain things behind a counter accessible only by employee, but the area is normally staffed.
When I shop, I am normally aware of the fact that there are probably cameras every where and while I am not inclined to steal things, I don't want to do anything that looks suspicious.
In the end, though, if stores are going to lock up some things there needs to be workers in place with a key.
