So how does she know she can trust what you say? If you do right by her, you may gain her trust, and earn a loyal customer, but the first time she walks through the door, she just doesn't know.
Oh, and women tend to feel this way more often than men, because they feel that merely by being a woman they are expected not to know about mechanical things, and therefore are targets for dishonest mechanics. Obviously women who DO know which end of a wrench touse don't have this fear, because if you explain it to them it makes sense, and anyway chances are if their brakes don't work they already know it.
+1.
also +1 on the sneaker comment.
when i was working in a shop, it took me a while to learn how to explain what i thought a customer needed
based on their needs, not on my own perception of what i would do in their shoes. obviously the OP's story is a more drastic example of that but i'd put it in the same category. most people don't need the most elegant, efficient, or ideal level of functioning, especially as appraised by a wrench or shophand. "i don't care, it works for me, and i couldn't be bothered" is a very natural reaction.
