I went to a resterant nearby with my grandma just now.We order some food with requesting no sugar in it,'cause my grandma couldn't eat some kind of sweet food.But when the waiter served that, we still found it's too sweet to eat.So I told the waiter to have a change of  it.He agreed,meanwhile he wanted to bring this back,immediately.I refused to let him do this,and explaint that I perferred to give him this,when I had the new one.meanwhile I wouldn't eat this one.

        But he insisted all long to get it away immediately.At the same time he told me that he would bring this back for serveing this to another consumer as soon as they could.Being honest, I was kinda like "Oh my gosh!!".Finally we found the manager to solve the problems.When we got the new one without sugar,we let them take it away.

       Some friends has told me that if u had problems of food in resterant,u should have keep quiet.'cause they are unwilling to bring it back,especially the terrible cook,they maybe will deal with ur food unimaginably/

       So have u met this issue in a resterant,how did u deal with it finally?
