You’ve agreed to a mortgage that you think is affordable. The lender gives you the papers to sign at closing. The documents include additional fees for credit insurance and other “benefits” that you did not request and that you don't want.
Hoping you won’t notice, the lender avoids explaining how much extra these monthly charges will cost you. If you do notice these charges, you might hesitate to object in fear of losing the loan altogether. Or perhaps the lender makes it sound as though the insurance “comes with” the loan, implying that there is no extra cost.
If you do protest, the lender may say that, if you don'’ want insurance on the loan, the papers will have to be rewritten and that the manager may reconsider the loan altogether.
