7-11's Joe DePinto

We caught this episode of "Undercover Boss" last night.
Normally, I abhor reality shows--because while they may be shows, I find them short on reality--but this one seemed different.
First off, it was about a real-life guy who's a real-life CEO of a company (7-11, the convenience store chain). DePinto pretended to be part of a documentary on entry-level workers. In truth, he was popping in on employees at four of his stores. Two worked the graveyard shift, and he worked alongside them.
Second, I was touched by each of the employees. Especially the woman named Dolores, who works the early-morning shift serving coffee to busy commuters. She knows most everyone by name. Meanwhile, she awaits a kidney transplant.
(My skeptical/cynical side is sure the employees were heavily screened ahead of time and these just weren't random visits. And, is there a monetary deal between CBS and the corporation? Because if not, that's a heck of a lot of PR for 7-11.)
