Uncooperative cashier with attitude

I went into pep stores to purchase clothes and when i got to the till i informed the cashier that i wanted to put the clothes on laybye and immediately her attitude changed. She started mumbling under her breath cursing that she hated to do that and kept grubling and complaining how much she hated serving me. She assumed because i was foreign s she was holding my paaspirt that i did not understand her unbeknown to her that i speak all 11 languages fluently. I asked her how much the total was and she didnt respond to me and instead kept asking me how much i was paying, how can i pay when i dont know how much the clothes amounted to?? After paying she practically threw the receipts three of them at me and told me to sign. I hd to tear up the receipts myself and sign i dint know which ones she was supposed to keep and when i held onto them she grabbed them from my hand and took hers abd left the one i was supposed to take on the counter and walked away in a huff. if she is not happy doing the job that she is paid to do she must quit or take it up with management not take it out on customers. I an seriously considering cancelling the laybye because of the bad attitude i received
