Target review: rude behaviour from target staff in electronics department

Today went to Target on Queens Boulevard in Queens NY to purchase a battery. The woman who assisted me was extremely rude and inappropriate. I first told her I needed a battery and she responded with "we have a lot of batteries, so what to you want exactly" her tone was rude. I explained and then she showed me what I wanted and I told her thanks, and that I wanted to look around the department. She sighed and appeared annoyed. I then completed looking around and went to pay. I paid with my debit card and added to have $20.00 off the card. She gave me $20., but it was torn nearly in half. I asked her for one that was not torn, and she said she was unable to open the register unless I made another purchase. I made a joke about was someone concerned about taking money out of the register. She then spoke loudly that I was now making a "big deal" out of it. There was another employee there who was earlier complaining about a client she was working with unable to speak English. By this time both employees were rolling their eyes at me and the first person was yelling at me as I walked away. WORST SERVICE EVER.
