Many times ! But I've just gotten to the age where I can tell if someone is trying to do that. It just doesn't bother me much anymore and I stay away from the people who have taken advantage of me. But there are always some who live their lives by taking advantage of others for their own gain. Fact of life. You just have to learn to spot it and walk away.
Sure, but I prefer it that way. On a personal level (not business) I trust people and usually that works out OK. I'll let anybody take advantage of me once. If I let them do it twice, I'm an idiot.
The only time I regretted it was when a close friend who had moved far away lost his house in a fire. I sent hm more money than I could afford to help out and only heard from him once after that. His wife visited six months later and admitted that they hadn't been able to sell the house so he had set fire to it himself.
He was apparently embarrassed about taking money from me as well as the insurance company and avoided my phone calls. But he wasn't so embarrassed that he felt obliged to return the money.
So I'm still a little upset about that, forty years later -- not because he ripped me off, but because I've had few close friends in my lifetime and we were very close.
Certainly, but I have no regrets. I'm not a doormat, but I would rather take a few chances on people than lie awake wondering if I could have helped. I have occasionally lost money and/or time, but I consider it an investment and move on.
Of course you live and learn but some people just are con artists so something bad will happen to them
