text: If you're a nervous kind of person who doesn't have the courage to talk to others, practice talking often to improve yourself so you can ask anything, anytime, without going through an emotional breakdown. And plus, even if you ask one or two people, you still could have a slightly biased opinion. That's why you should ask about 5 to 7 people on the subject of choice to get a true non biased, open, honest opinion. Also, certain subjects require more or less people. Asking if you can eat something could just require only 1 to 3 people.
