Bad service from every employee, don't know where their products are in the store and don't care, and tried to make me pay for extra item because cashier scanned one item twice. I was trying to get DMC floss for embroidery and it was my first time here. I asked about three employees because it was almost closing soon and didn't want to waste time looking for it. None of the workers knew what I was talking about and one of them even told me they didn't carry it. Frustated I walked around looking for it because the website said they carried it. I found the section and it was in such disarray and they didn't even carry more than half of the colors on the rack. The cashier seemed not too happy to check my items out. She clearly scanned one of my items twice and tried to play it off by pretending like I had 10 items and not 9. She was like, "You got 10 items right?" Right after scanning the item twice. I asked her to count again and turns out I have 9. Like, please remove that extra item. Not a good experience.
