New to Scottsdale, I needed a specific type of screws for my stool. I walked into the store on the lumber delivery side. After finding the goods, I went to the cashier closest to that door to check out. Since there was a customer with a lot of stuff, I ran over to the self-check out on the other side of the store. Quickly purchased the $1.24 screw, and ran back to the door I had entered. Just as I was leaving the store, a middle-age blonde woman (who was the cashier) came chasing after me asking if she could see the receipt. I showed it to her only to hear her tell me, "now I need to check your bag as well'. Hmmm, is this racial profiling? I only had my wallet with me and the screws (which weighed more like 3 oz) were in the plastic bag. I drove home not thinking anything of it. AS it turned out, the screws were not the right type so I had to return to the store to get something else. I told the head cashier in customer services and she apologized and let me know if was not 'normal' or acceptable behavior. I"ve been to other LOwes , HOme depot, and Ace and I"ve not been treated as such. Something to think about.
