A fair price should not depend on how uncomfortable the other person is asking for clarity.

Some pricing works by discomfort. The number stays vague, the extras appear late, and the whole arrangement relies on most people being too polite to interrupt and ask what something actually costs. Those who ask get one price and those who cannot bring themselves to ask get another, which means the difference is not about the work at all.

Put your number where it can be seen without a conversation. Say what is included and what is not before anyone has to ask twice. And when you are the buyer, remember that asking the price is not rude.
