It's funny to see so many customers walk into a store and assume that the employees are experts. This picture is one of the more egregious things I have seen. A certain salesman I despise was showing a customer how to use a mower jack, but he didn't even know how to use it himself. He was actually using it backwards, which is quite a feat when you consider how intuitive the jack actually is. After a few minutes of watching and laughing as this salesman tried to use the jack, the customer was rescued from certain harm and instructed on its proper use much to the salesman's chagrin.
