The new CBS show, Undercover Boss, continues to provide great insight into American corporations and lots of blog fodder. In the show, the chief executive of a major corporation goes undercover and tries out five frontline positions within his company. (There hasn't yet been a female executive.) The latest episode features Joe DePinto, CEO and President of 7-Eleven. Joe comes off as the least clueless executive so far, but there are still some gems in this show that are great lessons for any business person.
