The US had about 15000 stores. China has 6000... notvquite 100 :1. Korea, Japan, UK and Canada have over 1000 stores each.

Maybe a novelty in some countries...but certainly not all.

We don't have them at every corner, but every major trainstation, most shopping Centers and many touristy areas have one, if i want one it takes me like 15min walking/with public transport to get one in most areas im regularly at.

here in Tokyo at least there are like 10 different Starbucks-like local chains and they are all roughly the same price (i.e. expensive) so I think the point still applies, even if the stores aren't literally Starbucks branded. ordering coffee at a cafe here is fairly expensive.
