Of course, it depends. For a job working behind the counter at a retail
store that was, um, "geared" particularly toward ham radio equipment, parts,
and supplies being licensed was a requirement. A non-ham couldn't, among
other things, speak the language or have had any experience with the
equipment and antennas. Besides, only the hams were partaking in the
Saturday morning coffee and donuts. ;-)

In fact, I remember the newspaper help-wanted ad very specifically: "Ham
radio operator wanted for full-time counter sales."
