Bob Pogo is an angry, volatile, overweight man who is shown to have little respect for his employees, though he formed some sort of respect towards Frank after he was promoted to manager. He often struggles to move or breath, and is a heavy smoker. His greatest joy in life seems to come from junk food. He refers to the baggage handlers as "donkeys", leaves angry messages on Frank's answering machine and tactlessly fired Frank on Christmas Eve. Although he was instructed to do this by Dunbarton, he did enjoy rubbing it in Frank's face.
This caused Frank to lock him inside his car, dropping his keys at his feet where he couldn't reach. We later find out that Pogo was trapped for hours and had to soil himself to stay warm. He was eventually rescued, being pulled out of the car by the jaws of life. This incident also caused frostbite on his fingers, and the whole thing led to him trying to lose weight. He manages to lose enough so that he no longer needs his scooter to get around, but his diet is incredibly hard for him to stick to.
In the past, it seems that Bob was much nicer and had a friendship with Frank. He was much thinner despite still possessing similar eating habits. It would seem that as he aged, his metabolism caught up with him. He encourages Frank's dream of being a pilot, and talks about his own dream of having an office job with his own desk and a chair with wheels.
