Sheetz review: Customer service

I went into sheetz at 3am on jan 29th to order a iced drink because I have the flu. The employee at the restaurant was extremely rude and mean! She obviously had a mask on and she mumbled to me "do you want a receipt". I could not understand her so I said i'm sorry, what was that and she mumbled again. I said to her i'm sorry, I still don't understand what you are asking me. She literally threw something on the ground and mumbled yet again. I told her that she was being extremely rude and I told her thank you i'll just go get my drink. Then the girl who handed me my drink didn't thank me. She was silent and annoyed. Both girls were rude and it is unnecessary
