unprofessional cashier

On sunday 1 March we went to Edgars kollonade and bought two pairs of jeans. Looking for n paystation we saw the one at the cosmetics department and asked if we could pay here. With a a very bad attitude she told us no only if we purchased a cosmetic item as well and the with her hand she half heartedly waved in a direction that we had to go. I understand the logic behind that 100%, but the attitude really made me angry. In order to skip the long lines I decided to buy a R500 mosturiser which I needed anyway and went back to the station. She did not look like she wanted to help us at all and when she rang everything up she noticed one of the jeans didn't have a price tag and then she just looked at us with an irritated look on her face and told us there is no price tag. For a few seconds she just stared at us like it was our fault and when my husband eventually turned around to look for n price tag I told him to also look for the manager and then only did she make an effort to assist. I normally have no issue with going back and looking for the price tag myself, but her whole attitude was just so unprofessional that I felt greatly frustrated with her. Won't be going back there.
