The first few galettes I ate as a child back in the 70's I remember the fèves were quite large. Then as I suppose they went into more mass production they seemed to just use these small white plastic vaguely human shapes, like a tiny white plastic opaque jelly baby shape. In those days no one much cared about choking hazards in food. There were still coins in Christmas puddings for example. I always thought it was weird to put objects in food (even if the fève had the power to make you "King" for a day 😁)
Side note, this is why Kinder eggs are banned in the US because they contain a "non-nutritive object" that could be a choking hazard.
There's a relationship cheat code I use all the time. It usually stops everything in it's tracks and sets you on a much more positive path, especially if they're not used to you doing this. When you find yourself at that point in a conversation where you're about to shout something like "OH FFS! WHAT'S THE MATTER NOW?!" instead... you pause, look at them, tilt your head a bit, narrow your eyes thoughtfully and say as calmly as you can "What do you need?". No matter how mad they get after that you just keep asking that question until they respond to it. If you haven't done that before it may take them a while to even notice you asked that question. Just keep going. Oh also top tip... when they tell you what they need don't invalidate it. It's hard for a lot of people to directly tell you what they actually need. If they do then they're trusting you to listen. Breaking that trust will take you right back to square one.
