Years back living in 5x6m studio apartment block in Seoul we were woken up by a man trying to get into the aparmtent, banging on all the doors, at around 2am.
He tried all the doors a few times and was making a lot of noise, I got pissed off, went out to see him about to squat and shit on the stairs.
Grabbed the **** by the scruff of the neck, pulled him down the stairs, and chucked him out on the street. He was half being angry and half apologising, went back to bed.
In the morning, he must have returned, shat in the entrance way stairwell, where he must have slipped into his own crap, several times, as there were shitty hand prints over the floor, what was clearly someone having sat on their own crap falling over in a big smear, shitty foot prints, and hand prints on the door.
Nothing going upstairs, so I assume he was looking for a toilet. It was -25 so fairly chilly
Landlord was very apologetic.
