hey , Tom , did you enjoy your lunch ?   oh , don't mention it . It was terrible .   what ' the matter ?   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 .   I see . You simply can't blame the server for this .   yes , I know . Fast food is so popular in this district .   that's true .   anyway , how was your such , Catherine ?   it was good . I brough lunch from home today .   you did ? I thought you must feel right at home here as we get as many fast food restaurants as you do in America .   well , I personally don't like then because i don't believe they are healthy .   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 .   yes . I am wondering that you must believe fast food is your lifestyle , don't you ?
