Game in Springs Mall, rude staff

Game at Springs Mall has horrible staff. This is my second time there and it will be my last. One of the staff members(didn't catch her name), stopped my sister outside of the shop because she had a package from another store in her hand. The lady wanted to see a receipt. The receipt was with me and after I showed it to her she told us to just f... Off. This is highly inappropriate and totally uncalled for.
