Front staff is very rude. She wanted me to sign a document with a community pen that isn t being sanitized after each use. I asked front staff if I really needed to sign the receipt for my payment. She said yes ma am. I said y all should go to none signature like everyone else. Then proceeds to to throw receipt for it to slide across counter which almost fell to floor. I told her she was being rude.
