Up until I was 35ish ( 1990 ) there is no way I or my circle of friends would get ripped off by anyone ( mostly were drug deals since we never saw escorts then ),
Things are not like in the 90s anymore. Cameras are everywhere, evidence is much easier to gather. As much as i hate thieves and scam artist, i don't think anybody is willing to risk his life or freedom to "put karma on them". The rich folks who could hire a goon squad will not use those cheap avenues and if they happen to get scammed, they have so much money they won't really care.
The bikers and the mafias where always about violence to "teach a lesson" and keep peoples in check. If they let one guy go without paying a debt, everybody would do it. Its the principle and not the money itself. But when it comes to loose a few hundred $ trough an escort meeting gone sour, most rich folks won't care.
