I go to history events held monthly at the downtown library, in the afternoons. That means it's mostly retirees and me (it's an advantage of being self-employed and often, like now, working while at the library). They ask for 20 kronor for fika. While the organizers accept Swish, the large majority of attendees pay in cash.
