Ice-cream is one of those gorgeous things which make most devoted vegans forget about their principles, and those who are on a diet - struggle with the immense desire to buy at least one portion. So no wonder why those people who can't afford one will be happy to be treated by onyone else even if this kind person offers them just a bite, not a whole portion. But it's okay if such things happen between friends, but if you see two police officers licking the same ice-cream, would you be the same tolerant, ha?
