Why is there a check-in kiosk at your departure gate-- say, Gate 20 at SFO-- if you have to be ticketed, checked-in and holding your boarding pass to get through security to get to the departure gate to begin with?

Why is it that Rockstar caffeinated beverage is approximately $2.29 per can, whereas the same size can of "Rockstar 21", the alcoholic version, is $1.69?

Why do I have to punish myself by waking up at 3:00am when getting out of bed is most assuredly NOT my specialty by any stretch of the imagination? Oh right, because I work at 4:30. KILL ME.
