Always amazes me how rudely the ppl in this manga is stealing (or rather, rob, as its by gunpoint and not stealthy) the guys sugar that he paid for himself (its not merely pressuring him to do it, they appropriate it even if he says no repeatedly), a luxury good that costs a damn lot due to their location and technology. A modern day analogy would be if you worked at some place and your coworkers always thought it appropriate to force you to give them your cars gasoline, or your expensive skin care products/cosmetics or... special imported alcoholic beverages (no clue why you brought that to work, you damn alcoholic).
