Children's Place

This is in regards to my recent experience at Children's Place Cumberland Mall Atlanta, GA on July 24, 2019 at 11:30 am. I arrived to pickup my online purchase and I was asked for my ID. I explained to the clerk at the counter that I had left my ID in my other vehicle. She then said to me "well can't you just go to your car and get it". I said to her that I couldn't because it was at home in my other vehicle and I drove a different car today.
I asked her if I could show her my confirmation email and she said that it was unacceptable. I explained to her that I've used my confirmation email before. She she looked at me and said "well I guess you just have to come back, have a blessed day".
I am just blown away at how rude and impatient this woman was with a customer. After being spoken to someone harshly, I don't even want to return and get my order. I'd rather just have my money back. Children's Place has lost a valuable customer.
