Imprudent make up assistant

I went to edgars in the johannesburg cbd on the 31/03/2018 to the estee lauder assistant (her name is Tumi or Itumeleng looks like shes in her forties )to ask her for a caramel make up sample to mix with the Amber honey im currently using since ive changed facial products and have gotten lighter complexion from using them.Which in turn the make is now a darker shade. I got to the estee lauder assistant who was busy doing a face beat and greeted and told her need a caramel make up sample which suddenly her face changed so i explained why i was asking for it and that i was happy to go fetch the make up n show her its become dark.Which she seemed less interested in and contimued with the face beat and i told me about having red undertones which was really irrelevant as i have a olive undertone. She then continued doing the make up whilst i stood there after about 10mins said shes waiting for me to go fetch the make up so i told her it doesnt make sense to go fetch the make up since she has a amber honey sample she can apply it on me to see that its dark and that i have had the same issue in the past and got a caramel.sample mixed it up and it gave me a proper colour. Which she responded by telling me shes still busy with the facebeat she'll deal with me afterwards which she kept me waiting for an entire 30mins till i eventually decided to leave. What got to me was her attitude the min i asked for the sample her entire attitude changed now i need to understd why does estee lauder give them samples if its such a issue for them to give to clients isnt the purpose of these samples for clients to be able to tryout and see which colour is best for their skin. As for keeping me waiting for 30mins whilst the samples where right infront of her and wldnt have even taken her 5mins to pour. When i eventuallt decided to leave she had the odesity of telling me she knocks of at 4:30pm i should come back then. Ive never had such attitude or problems with ur shop attendants at the mall and u cant keep some1 waiting for 30mins when what she needs isnt even 5mins. Im really disappointed and amazed at the attitude and bad service i recieved from this woman and hope she doesnt treat other clients in this manner when they ask for samples.
