Don't rush the borrowers
Before you set foot in your car, tell the borrowers the time parameters of their appoinment. Tell them, "I can
be there from 8pm to 9pm. If we don't finish the signing by then, we can reschedule the appointment. Do you think you will be able to sign all of the documents within that time span?". If the answer is no, then cancel the appointment unless you want to sit for three hours babysitting them while they read ever word of every page in a 100 page loan signing. Tell the borrowers that they can read their borrower's copies and that they have three days to cancel the loan if they find anything they don't like.
