Anybody who hires small time contractors, has a landlord who hasn't upgraded to electronic payments, or wants to send a sizeable amount of money to a family member. I hate writing checks and I avoid it whenever I can, but as a homeowner I have to write checks to pay my property taxes at a bare minimum, and whenever I hire an excavator, plumber, or other tradesperson there is a good chance they are going to want a check or cash.
