now asking people you invited for money to cover your expenses, certainly is not normal in most of the world
apples and oranges, you are mixing up two completely different things
and these people are not really inviting friends or people they know to their place, they just run some small stand from their own home to make money, completely different ocassion/event than having a (birthday) party
There are probably millions of child lemonade stands in the US. I think you must be referring to a story where one family was asked to take down theirs for some reason.
The reason that story was written and is memorable is because it's so whacky and unusual. I expect my kids to run lemonade stands with no complications:)
Get your facts straight. This is the EU-way. It literally happened in Poland - a child got fined for a lemonade stand.
