WTF is going on at DQ?

It's been well below zero recently, and yet the DQ on Lake street was open today, with people standing around outside waiting to order ice cream. What the hell, how is it they planned ahead and hired staff to make ice cream in February? And what's with the idiots (including me) who stop for ice cream when it hits 30 degrees? While I was waiting for my misty freeze and marveling at the crazy weather, I did ask the guy behind the window what he thought of global warming and he told me, "IT SUCKS!!!" (Which was a lot funnier if you're the type of person who repeatedly drives to Baldwin, WI for basically no reason.)
