Amy was pissing me off , though .. This morning after I we had walked all the way to customer service , the doorbell rang . She had ME go get it because she did n't know who it was . And since I was super cranky , I was thinking to myself , " Oh great , so if it 's some mass murderer at the door , better you than me , right ? grumblegrumble " .

Question: Why is the narrator perturbed at Amy ?
Answer: Amy wo n't do customer service .Amy wo n't open the door for someone .Amy wo n't stop being cranky .Amy wo n't stop being pissed off .
