I remember, a whole buncha years ago, handing an NYC shop a $10 for a pair of 75 cent cans of soda and being rewarded with a look that said, 'what the fuck do you expect me to do with that?'. The girl I was with, who lived in and spent much more time in NYC than I, immediately recognized the meaning beind the look and dug out something smaller before I even added up what was going on. Left on my own I would have taken the 10-spot back and spent it somewhere else. Sweden is one of those places on the leading edge of the trend towards going mostly cash-less, so best to check on specifics before visiting CPF headquarters if that pocketful of Krona will even get you in the door.
