Chicagoans is a first-person account from off the beaten track, as told to Anne Ford. This week’s Chicagoan is Patrick O’Malley, 51, doorman.

“I was a floor trader at the Chicago Mercantile Exchange before I became a doorman. I loved it; it was just very stressful. By the time I did my eight years down there, I was burned out. There’s a lot of money going around, and things can be easily misconstrued, so I might tell you that I’m gonna sell you five, and things are so crazy you might say, ‘Oh, you just sold me 50,’ so you better have the money for 50. You always have to have the wherewithal in your mind to know the money you’re playing with. It’s very stressful to be on top of all that every second.
