Light Versus Dark

if i had a quarter for every time a customer asked for the "darkest roast you have" i would take up residence at an arcade and play frogger until i lost consciousness... oh wait, i already did that back in the 80's. alot of people think that a darker roast equals more caffeine. what do you think? does a darker roast have more caffeine, or will a lighter roast get your coffee buzz going? if you know the right answer you'll get double punches toward a free drink! the answer to last week's trivia question is 3000 gallons.
