Is this legal on the NYC subway? On the DC metro, eating is forbidden and enforced. I remember a story from years back about a little girl being led away in handcuffs for eating a few french fries. Hopefully this story won't get him into too much trouble.
And hopefully it won't spawn too many copycats either. The last thing this guy (not too mention the other riders) need is for the number of people peddling sugar to multiply.
