Q: In this task, you're given a context passage. Your job is to generate relevant questions that can be answered by directly referring to the passage.
I went to a restaurant with my grandpa a couple of days ago.  It isn't a restaurant that has very good food or very good service, so I wasn't sure if it would be good.  When I ordered my food, it took a long time to get out to me.  When the food was finished and I took my first bite, my burger was very cold.  I tried to get a hold of the waitress who brought us our food.  I asked her kindly if she would be able to make sure that I had a burger that was warm.  She apologized for everything and told me that she could have a warm burger ready for me in just a few minutes.  After about ten or so minutes, the food came back out to me and it was a lot better tasting this time around.  I'm glad I asked for a new one.
A:
How did they act when sending the food back?
