You just described a young mother I recently saw in a waiting room, only in addition to a similar manner of dress, she was slurping some kind of slushy thing.
The two kids in tow were around ages 5 and 7. Each had a bag of chips, wandering around the room, munching away and leaving crumb trails (never mind all the "No Food or Drink" signs).
The kids were still normal weight, but with the have-no-respect-for-yourself-or-others, pay-no-attention-to-rules-and-decorum, snack-no-matter-where-you-are learned lifestyle, that'll change in short order. Ugh.
Were they in cursive??
