I am not usually worried about a soda, but this place is way beyond anything with the peanut butter in several shakes. And it sounds like they do tons of shakes, it is their "thing."
Dd has been places with *us* and not eaten! There was the time she forgot her epipens when we went off to the mall. Maybe 5th grade? we had reminded her, and she somehow set them down again, or forgot. We had planned on having lunch as a family. We still needed to feed ds, as he was hungry and young. Not fair to starve him for her error. So, we got him pizza in the food court. She was very hungry, since we had planned on having lunch. It was a lesson.
Also, we have often brought food or simple snacks in place of buying her food at parks, etc... when we are headed into unknown territory. She is ok with that, as a family.
However, she does seem bummed at the thought of hanging and not getting something. It just does not seem fun. And she has made a poor decision or two, the couple of times I have let her go alone with friends to Dunkin Donuts. Took a blender drink from a friend, when friend did not like it. And oreo Coolatta. Not sure if they do anything nutty on the blender, but she knew nothing of the item, since she had not ordered it for herself. We discussed all of this. And the sharing of the straw, not knowing what friend had eaten that day.
She still is young or immature wrt to making impulsive decisions. Well, I am guessing that is age-appropriate, seeing as that brain function does not mature entirely until around 25 years old.
We will see and discuss if she gets invited to go there. I would not want her having anything until I go see the place. I do think we ate at one years ago. In Florida, at a retirement "village." It was very clean looking, as I recall. I also think all the PB shakes would not be so big with the senior set. It was likely our only real choice at the time and I am sure I had no awareness of their big thing with the shakes.
