Technically yes. But it kind of stands out. I personally never drank any caffeinated beverages on campus because some people seemed uncomfortable with it.
I drank coke all the time on campus. Nobody ever seemed to care.
Actually, the only time anyone has ever given me crap about drinking coke was one of my mission comps who freaked out about it, so I drank a 2 liter of coke every day for the entire time I was with the dingbat.
