Ross Dress for Less

it was about 11:10 am on Tuesday October 29th 2019, I was in the checkout line, the line was long and there was a line for returns as well. there was only one employee at the register. her name was Erin and she looked to be about 40 years old. I asked her politely if there were any other employees that could help with the lines, she told me there was only one other employee working and that she was on her break. when I got to the register I said you know I highly doubt theres only one other employee working here that would be rather unprofessional and she said "that's okay you dont have to believe me" I then said I could have been home by now studying, she responded by saying "then maybe you should be home studying instead". I told her that she was being rude and she responded by saying "oh I'm never rude to customers", other customers were chuckling at the way she was treating me in disbelief. she was rude and unprofessional I dont ever want to go back there and have to interact with her again.
