This is not because of any superiority complex as is being alleged by you. This is because of the smell and the possible poor maintenance of the house. Bernard Shaw once wrote: "If you want to be a Sancho Pancha, you can eat fish, fowl or flesh so long as you have enough of it. Only if you want to be a Pythagoras, you have to be more careful with your food". Those are the words of a great scholar of the 20th century.
