wild caddies on Helsinki streets

for last 9+ years living in Greater Helsinki area, I have seen only very few abandoned shop caddies on the street - coin in lock made them "magically" returned to closest shop

so I didn't pay much attention apart from little "woah" first time and making shot


second time it was late evening, coming out with friend from local pub - I got little puzzled... and shot it again.


and last time it was two days ago - on the corner of office building


looks like they are surrounding me... or trying to say something? ;)
