You have your experience and I have mine, and really no need to make assumptions. I'm not making any assumptions about how you present yourself to get a kid's meal.
Excuses are ... folks giving reasons why they shouldn't have to pay for an adult meal.
We parked for free at hotels for decades, no more.
We got FP free for decades, no more.
Stuff changes.
Chapek is monetizing everything.
LOTS HAS CHANGED! This is Chapek's Disney and he doesn't plan on leaving money on the table or letting guests wiggle out of paying for stuff. We have no idea what their breaking point is, but I can certainly see this being one. We are talking here because guests are experiencing changes.
Dining at TS restaurants is optional. Don't eat in them. Hotels are not optional. I don't want to pay the same as a family of four in a hotel room for DS and I. We use less water, less towels, less seats on the bus ... I can't get a discount.
It's not something I want to continue to banter. This is all your opinion, my opinion and neither matter only what Disney is trying to do. Plenty of places to get some food, we all find those that work for us.
But if guests continue to take up tables and try to reduce their bill by eating children's meals or sharing meals then Chapek Disney at some point may make changes. I was just suggesting some ways they might do it on top of what OP experienced.
Look at BOG. Guests abused the system so it got changed to prix fixe. Still a busy restaurant and that is all they need to see. It didn't hurt them.
Remember when every blog told you to order just a bun for 50 cents at quick serve with double burgers? Yup, Disney caught on and stopped it. Was great for 50 cents you got another burger and with the fixins' bars a sweet meal. Folks even made FREE salads from the fixins' bars. I doubt they will be back.
