This one cashier lady at cvs made me upset beacuse?

I dont know why but i accidently interuppted her when she was going to tell me the amount total of my purchases and asked if she had any change and responded by saying do i have any change and she also said do you wanna buy quarters/change then waited to pay for my stuff then after i paid. she didnt give me the reciept to me by hand she placed it next to my stuff then rudely not even looking at me or saying thank you gave me my change. How bizzare and unprofessional is that?
