I could swear I've seen them in Chicago (when did you move there, by the way?) but maybe I'm thinking of Dunkin Donuts. I know, they're really different things. Out in the MSP area, you didn't really see either. Denver has 7-11s all over, but I haven't really been in one yet. However, I found that one of those giant girly daquiris in LAS kept me pretty cool, even if the sugar messed up my stomach the next day (wasn't a normal alcohol hangover, just a stomach feels like crap kind of thing)
