I haven't had nearly the poor experience the other reviewers had, but I also never go in expecting much. Everyone I have spoken to was pleasant, and a couple helped me find things I needed. They always ask how I'm doing and if I need help and seem fairly genuine about it. Checkout isn't bad at all, they always seem to have enough cashiers to manage the line of customers.
If you want to feel appreciated for your purchase of higher end products (Urban Decay, Clinique, etc.), to go a department store or even Sephora. Everything else is drugstore brand/quality so why would you be expecting the white glove treatment for $7 mascara?
