I definitely agree about the service depending on who is serving you.
Some of the sales associates are unfortunately clueless when it comes to their stock, brands and products. I went in looking for a pair of Asics running pants... one of the sales associates barely looked and told me they didn't have them in stock and that they didn't even carry Asics apparel (when she said that I knew she was a few crayons short of a box)
so I spoke with another sales associate and sure enough he found me the exact pants I was looking for.
This is still my favorite running room location
