Input:  Person1:     hey , Tom , did you enjoy your lunch ?  
 Person2:  oh , don't mention it . It was terrible .  
 Person1:      what ' the matter ?  
 Person2:  the food station was as crowded as usual . I waited for 20 minutes for my sandwich , and when I finally got it the chicken was underdone .  
 Person1:      I see . You simply can't blame the server for this .  
 Person2:  yes , I know . Fast food is so popular in this district .  
 Person1:      that's true .  
 Person2:  anyway , how was your such , Catherine ?  
 Person1:      it was good . I brough lunch from home today .  
 Person2:  you did ? I thought you must feel right at home here as we get as many fast food restaurants as you do in America .  
 Person1:      well , I personally don't like then because i don't believe they are healthy .  
 Person2:  i guess you're right . More often than not , people go there only for convenience . The foods may taste good , but generally speaking , they are high in calories , salt and fat .  
 Person1:      yes . I am wondering that you must believe fast food is your lifestyle , don't you ?  
 Person2:  you bet . Almost all top brands such as McDonald's and KFC are from America .  
 Person1:      well , actually two-thirds of Americans may avoid these places .  
 Person2:  seriously ?  
 Person1:      yeah , it's hard to believe but true .
