My wife is very good at asking questions. She likes to ask nicely about discounts when shopping and frequently either gets a discount or gets good advice about one - eg "We don't have one now, but usually in June we have a good sale, come back in a month". When people ask my business for a discount I always offer one to people who ask nicely.
