One tell-tale sign of a newcomer is that they'll beg by telling you that they're not thieves, not trying to trick anyone; they just want to eat.
And you'll look up & down the long line of mums out with their babies, the elderly, the disabled, the down-and-out youth, & think incredulously... no one here is trying to thieve by begging with candies. Everyone's just trying to eat.
But they haven't fully adjusted yet.
They will.
They always do.
But being looked at like scum when in need is *hard*.
