Appaling behavior from staff

The disrespect we get from our fellow black people is appalling!! I went to go test for make up.. I tested for estee lauder and i asked for a sample as it is written on the shelf... I was told they dont have any while it was right infront of me. I was treated like a nobody who is wasting their time... Mind you im getting paid and im looking for a good make up brand. I felt so disrespected. The treatment i got was disgusting.. Its not even about the free sample its about the way they looked down on me!
