drink they like because of the taste, it sounds weird to me. Like a drug addict asking for more. I used to drink chimarrao on the mission sometimes as well. Didn't even know about the caffeine content and really didn't love it but it open doors with the members and non-members a like.
I don't have a problem with people wanting Dr. Pepper or Coke or whatever. When they are calling for caffeine I just think, "take a pill before you get there if you need it that bad."
All this reminiscing about Brazil makes me think it is time to go to Macey's and find a 2 liter guarana. Maybe I can find decaf
