I go to Sephora because they have the best products at even prices of a department store, plus you get beauty insider points. However, usually I feel very judged when I go in here. I don't slap on make up heavy but I have my few go to's which keeps me coming back. There's A LOT of employees here but a few times they are hard to find when you need one. I've had a few girls be super helpful, lots of samples etc, then some are terrible and don't want to help at all.
As for beauty insider points, they need to get better gifts to exchange your points for. I have so many because it's never worth it.
Treat everyone the same, get employees that are willing to help everyone and I'd have nothing to complain about.
