== Elimination of taboos == 

 "McDonald's led to the easing or elimination of various taboos, such as eating while walking in Japan." 

 Well, I've lived in Japan for six years now and I have to say that eating while walking is still very much a taboo in the sense that: 
 1. It is almost never seen 
 2. Parents teach their children not to do it 
 3. You are stared at if you do it
