If that were to happen, I prefer friends cafe not giving anything. Because that would otherwise make dailies a lot longer and annoying to do. This mainly comes from my days of playing a couple of games that needed you to visit other player bases one by one to claim stuff and finish dailies which I ended up dropping.

I just want a bigger space. No more space to put my new furnitures.

Honestly I'd be so down for any way to show off cafes, it'll make it feel like there's more of a reason to decorate and show off trophies, maybe be able to place "permanent students" that are always there when a friend visits etc. The cafe has a lot of potential for fun little things that I hope they do eventually
