It’s a chain restaurant. Funny thing to build family traditions around, it’s not like a 300yo family run pub that has been serving a community for time immemorial.
But yes, people have things they like. They like when things they consider good don't do total overhauls. There's a very good chance you have something you hold dear or would be upset if it changed, and others will happily mock your frustration.
Not everyone is so lucky to have a 300 year old family run pub nearby.
So maybe find some more empathy for people's lives growing up? Nobody chooses the situation they're born into.
