Cashier didnt talk to me and rolled her eyes at me

Today at 5pm i went to buy at the kiosk and do a cash back transaction, upon reaching the kiosk after standing in a long line i was told that the POS doesn't work, i then asked the cashier to take me to one of the tellers with a pack of cigarettes as i cannot do that myself, she did that. When we got to the teller, who is pregnant lady, the teller asked her to help us but shr didn't respond she just looked away. Wgen she finished with the customer she was serving very rudely too ( she flung the pos machine to the customer ) she took the pack of cigarettes without looking at me, i greeted her and asked for a cash back and she just ignored me. I then asked in a louder tone thinking she didn't hear me but shr ignored me and kept talking to the lady who was packing groceries into plastics. They kept saying \i don't have time for her""
