I have to say I agree with the comments about bad manners. You feel there are some cultural differences when you walk into this place. However, all in all they are not bad.
To me it seems that the employees are more disinterested than malicious. I've been several times and only had good recommendations. Know what you want before you go to the store. They are honest about what they have, and what they can get.
I would hesitate to think you can go to a beauty store and expect they aren't going to try to make a sale. If you don't know what you want be sure of what you don't want. It makes the process much easier. When you are direct and say either YES or NO then you will leave happy. Leave the maybes for someone else.
