Stroller or Leash?

I was working out on the recumbent bike which faces the entrance of the community center. I noticed a woman walking toward the doors with three small children in tow all attached to leashes. Each child's wrist had a band around it that had a white strap going straight into the mother's hand.

I know some parents think this sort of device is ok. I have three Marbles. I know how hard it is to make sure they are safe in parking lots and stores. I know how they get under people's feet and go every which way, but never, NEVER would I resort to putting my Marbles on a leash to keep them close to me.

This twat had one kid who was starting to stray and go toward the exit doors. Instead of reaching over to grab the child's arm and lead them in the entrance, she yanks the leash which jerks the kids arm and he turns like a dog and follows his mother. Once she is at the check-in desk, the kids, who are under three, are just standing there still connected to the leash. The mom is trying to get her card out which would have been pretty easy if she didn't have to hold onto three leashes.

I wasn't sure what she was going to do next with her pets kids. I could have sworn she tied them up to the treadmill and told them to sit and stay while she did her three miles on the treadmill. She was throwing Cheerio's at them which they caught in their mouths and then had little bowls of water laid out on the floor for them if they got thirsty. Once she got to her last half mile the animals kids started getting fussy so she threw them squeaky toys and Scooby Snacks to keep them content until she finished her workout. The mother seemed offended when this woman who had three children of her own with her and pregnant with a fourth came up to her and asked if she could pet her dogs kids. But, I mean, they were on leashes, tied to a treadmill, with squeaky toys and little bowls of water, I could understand how she might have been mistaken. Couldn't you?
