I'm a Norwegian who went to a Swedish music festival last summer.
I couldn't pay for a lot of things there, since the booths only accepted Swish (the only relevant Swedish mobile payment solution, it's a de facto monopoly). I couldn't sign up and use Swish on my phone, since it only accepts Swedish bank accounts. I couldn't borrow money from my Swedish friends either, since they didn't have cash (and it mostly wasn't accepted at the festival anyway).
When I could get someone to pay for me directly, transferring the money back to them was hard (since the festival didn't have any ATMs), so I had to go through the whole burdensome SWIFT procedure with getting their bank account number, their full name and address, their bank info, IBAN number of their bank etc, so I could send the money back when I got home to Norway.
