I'm guessing which of the two you get will have a big effect on your experience as a customer.
Funny story: Management often put me on the cash register guarding the entrance/exit to Tool World because I was very thorough in checking customers as they exited; there was a big problem back then with customers stealing small high-value tools by putting them inside other, less-expensive products. So, it was my job to prevent that. Anyways, I didn't know much about tools, but there was a girl about my age who was very knowledgeable in that area. She was the Tool World expert who roamed around the section. One day, a contractor came up to me at the cash register and asked me some very specific tool-related questions. I had no idea; I said, "I'll call the expert in to help." He said okay and waited. When he saw this young girl with glasses walk up, he looked at me and said, "you've got to be kidding me?"...then he walked away and left! Funny thing is that she probably could have helped him!
