The door lock where we stayed was problematic. From the outside, you had to turn the key just right and press the handle at the same time to get in. I’m sure it stopped many a would be thief.
Getting out was a bit easier. You just pulled that bit on the left and then opened. It’s pure Croat genius in that, because I mean, really, why pay a proper locksmith to fix the thing, when you can wrap an old coat hanger with a bit of electrical wire for a handle to pull out the lock mechanism? I’d bet good money there were a pair of needle nose pliers stuck in there for years before this came about though.
