I'm pretty sure the employees are quizzed on locations of obscure items to keep them on their toes. I have yet to be answered with the puzzled look you find at ALL big box stores. I do think that the frequent check-ons by staff can be a bit overbearing but it's all done with good intention. Lastly, I am always shocked by how much stuff they carry. Don't let the size of the store fool you! They have it all.
