Slurpee Capital of the World - again!

This is just crazy, apparently my city (Winnipeg, Manitoba Canada) is the Slurpee Capital of the World for the 10th straight year! (well according to 7-11 sales). Here's a news article from my local newspaper:

http://www.winnipegfreepress.com/local/10-years-of-brain-freeze-were-no-1-slurpee-sippers-again-50347352.html

quote: "Specific numbers aren't available, but Winnipeg sold 20 per cent more Slurpees than Calgary, which finished second. Southwest Detroit placed third."

What makes this extremely crazy is that Slurpee sales remain good throughout the year, including the winters where it is commonly as cold as -30'C (-22'F) and even as cold as -40'C (-40'F)! How do people even want to drink a slushy cold drink in those conditions? LOL.

I was a multi-visit per day patron of my local 7-11 in my high school days (it was a 5 min walk away from the school), but I was more of a Super Big Gulp guy rather than a Slurpee guy.
