It's rude to take advantage of a friend.
Since Josh has been sick with a cold for a week, his friend Ana often stops by to make sure he is okay and drops off soup.
Josh wants Ana to pick up his favorite takeout food since he is unable to do so.
Josh kindly asks Ana if she will pick up some food for him and thanks her immensely, offering her a gift card for her help.
Josh sends Ana out for food every day without ever thanking her or paying her back, even complaining about his orders being wrong.
Ana feels appreciated and continues to help Josh through his cold.
Ana feels used by Josh and stops talking to him.
