Crap Hostels - Your worst travel stories...

Well, I have had a few hostel experiences but here's one example of nonexistent or uncaring management.
Myself and another guest are happily asleep in a 3 bed dorm room in a 2 bedroom apt style unit, it's about 3 am. The 3rd guest comes in with a non guest female friend and wakes us both up.
They proceed to have sex about 3 feet away from my face, squeak, squeak, squeak.
I sit up and ask him nicely if he wouldn't mind going out to the empty living room and using the privacy of the sofa there.
He looks annoyed, smiles and says "sure" while the girl continues to straddle him like a horse and it's apparent he isn't going to do anything of the sort.
I say "No, man, I have to get up early, so...ah, please stop." He tells me to "F--k off", so I make the mistake of telling him to "grow up". He then gets out of the cot and grabs me around the neck, at which point I implore him, "I didn't come here to fight, I just want to get some sleep". I managed to hold him off but by then other people are also awakened and present so he stops assaulting me. Now I do not feel safe around this person, sleep is now pretty much out of the question and I tell him that he needs to leave or I am calling the police and pressing charges. He refuses to leave so I pullout my cellphone to call 911. At that point 3 other guests in the apartment relate to me that they would rather I not do that, the reason being that they are in the country illegally.
Well, fine, you tell this guy he has to leave. After 30 min of arguing with him, he finally leaves. You are probably wondering where the management is during this incident. Well they do not live at the 40 bed hostel and I tried calling their number but I guess they were off the clock.
The next day I left a note on the office door concerning what happened and why I did not call the police. When I returned that evening, tired, I saw the same miscreant giving me the evil eye.
It seems they just moved him to another room.
When I asked the "trailer trash" in the office why, she tells me that he was "way behind on his rent and they cannot let him leave now."
Oh I see - rule abiding, considerate, paying guests take second place to criminal, lowlife, nonpaying guests.
