OK to ask lender for example Loan Estimate?

[Jason H.]

These lenders make all kinds of claims... is it ok to ask for an example/typical TRID-conforming Loan Estimate in order to see all the details of a particular loan product?

I've been told by a lender they do not charge any fees or points. I assume this means Section A "Origination Charges" on pg 2 of the LE would be $0.00. But Sections B and C would still have fees there and I'm curious what they are.
