Well Yes, in a way.

My husband was chief of a team of forest rangers and they wanted to hire someone new. He got to choose and he had just met someone he thought would be a good person, Alex.

Alex was married, no children was a shop owner and helped his mother in law out at a gas station.
Alex got hired but every two years when the team changed president and board members they wanted to fire him because he did not work at all.
All he really did was get into the car next to my husband, drive along for seven or eight hours and watch his cell phone. When things got tough Alex would hide, walking to the crime scene when the danger was over.
My husband thought nothing of it because outside the job Alex was a good friend.
So every two years my husband put up a fight to keep Alex in the team which cost him the relationships with the new board members but he did not care.
Alex, however would never stick up for himself, he would even become friends with all of them.
Five years into the situation I became friends with his wife, Tina, as well, and we spend a lot of time together. We even went on holidays all together.

They would lie to us, cheating us out of money, hiding events etc. We slowly became aware of their true nature.
On our last trip a family member of them told my daughter that we had to be careful of what we told them because Tina was telling her all our private stuff.

I had had enough. When Tina phoned to give me an earful of how my daughter was not supposed to talk to her sister in law, I told her what I had just found out and hung up.
A week later I heard from another colleague of my husband that Tina had called the wives of every one of the team and lied about things I had said about them.
Luckily most of them did not believe her but one woman would not speak to me again.
That same woman and her husband went on a holiday to Asia with Alex and Tina a year later. Turned out they had being going out all the time we were friends and we never found out.

Anyway, the “revenge” if you can call it that way is that they posted pictures of their trip on Facebook where Alex’s brothers discovered that there brother who always told them he could not provide for their ill mother and never had any money to help them out, was happily smiling on a expensive trip.
They called him out on it, he had to travel to the main city and help out. Due to that he was forced to resign.
