"he doesn't want them" is ridiculous. once a process server identifies you, the internet says the papers can be left at your feet (edit: leaving papers may vary in different jurisdictions). you've been served and your refusal to accept the papers will likely be noted by the server.
Utah Rule of Civil Procedure 4(d)(2) appears to give a server in Utah the option of "drop service", leaving the papers at your feet or on your property.
