Please fire me. A customer came in and yelled at me that he was reporting us to the state because all 3 parakeets he has bought from our store had died. Upon further inquiry, he admitted he neglected to feed them anything. When told that parakeets need food to survive, he was shocked and told me I should have told him that when he bought them.
