I saw atleast 5-6, also few people with miniguns in second slot killing people there for the lulz.
Damn sounds like you had some bad luck, the worst I've seen is people getting lured into the back room.
Getting lured to a roofless hovel, where plaster falls off from moulded walls, window has been broken for god knows how long, and the only furniture is a ragged, stained mattress? Sexy, very sexy.
