If you read Kessler's books, you'll find
Biden liked to go skinny-dipping, much to the discomfort of SS agents who indentified were female women.
He's a cheapskate - never having cash on hand to tip waiters, etc, and "borrowing" money from the agents.
He portrays himself as a "regular guy" while being careless with national security.
He likes to fly
“Agents believe Biden insists on only two vehicles in his motorcade in Delaware because he wants to maintain his image back home as a regular Joe. But besides rendering the country potentially defenseless in the event of a nuclear attack, “he is making the agents vulnerable by not respecting what they need to do and making him more vulnerable in case of an attack on him,” an agent says. “If the bad guy knows that they’re rolling up there short and there’s only two vehicles, it’s easy to spot, and it’s easy to take him out. He would be a sitting duck.”
Thus, according to Secret Service agents, Biden seems to care more about his image than carrying out the only significant responsibility required of him as vice president: to launch retaliatory strikes in the event of a nuclear attack. That dwarfs the only duty the U.S. Constitution assigns to him—choosing whether to vote in the Senate to break a tie.”
“Agents say that, whether at the vice president’s residence or at his home in Delaware, Biden has a habit of swimming in his pool nude. Female Secret Service agents find that offensive.

“The records show Biden thinks nothing of flying back and forth to Wilmington multiple times on the same day. For example, on Friday, February 8, 2013, Biden flew from Andrews to Wilmington and back to Andrews on a C-37A, then returned that same day to Wilmington on a C-20B. Since deadhead flights were required to pick him up or drop him off, that taxi service entailed four flights in one day at taxpayer expense.”
“Vice President Joe Biden may seek to project the image of a regular Joe, friend of the workingman, but Secret Service agents know a different Joe. That Joe champions cutting government waste while spending a million dollars since taking office on personal trips back and forth to his home in Delaware at taxpayer expense.
At least once a week, Biden takes a helicopter designated as Marine Two from the vice president’s residence to Joint Base Andrews in Maryland. He then hops on Air Force Two to jet back to his home in Delaware. He returns to Washington on Air Force Two. The cost of the flights is doubled because after dropping him off in Delaware or picking him up at Andrews, the Air Force has to fly the plane empty.”
