Are we supposed to sit down and buy something the moment we enter a high figh cafe?

So there was this cafe I once ordered food from years ago. Well, pastries actually and they were amazing. We sat down, ate, went home. Today, I revisited the cafe in search of those pastries but they removed that section, so the my travel companion (she is older than me) insisted me to order something, I saw the menu and it was pricey. And I didn't wanna spend much. So we left. While on the road my companion said that when you enter a cafe you are supposed to sit down and order something. It doesn't look good to just enter a cafe and leave. What do you say? What would you do?

Yeah, you should have bought something.
It's okay to leave
It's okay to leave unless you occupy a table
Girl, why did you enter without prior knowledge?
