My father's department at work had a number that was one different from a pizza parlor, and he and his co-workers would cheerfully "take orders"/screw around with callers.
Herbert Solow and Robert Justman's book Inside Star Trek details this, too. So, yeah, it happened. Gene Roddenberry had his good points, but he was a money-grubber.
My father worked at an ABC network affiliate, and saw then ABC anchorman Peter Jennings doing the same thing while reporting from a motel balcony somewhere. (The viewers at home didn't see it..)
Pete Ross turned up as a character on the TV show Smallville; in some quarters, he earned the nickname "Product Placement Pete", for his relentless in-character shilling of sponsors' products. (Maybe that was his real superpower all along..)
But of course, they ain't gonna include anything by a horror author..
"There. How do I look?"
"Like a cheap French harlot."
"FRENCH!?"
This attitude really annoys me. Purses are -useful-. But no, I'm only a man if I cram all my stuff into sixteen pockets instead..
