I got scammed.

It was a few weeks ago during lunch hour, and as I realized what happened I sat down to write an e-mail about it to keep myself from going back outside to look for the guy. Here's the message:

I just finished getting soaked for another twenty while walking back from Subway. As before, as each minute passed from the completion of the transaction, my confidence in not having been scammed dropped from about 90% to something below 50%. I record this story as a case study with the goal of forming actionable goals should this situation arise again.

So I was on the short walk to the office on E Street from Subway on a nearby corner, wondering why cash register drawers still pop open at the conclusion of a credit card payment, as they have since I worked in retail.

A guy positioned himself alongside my path and began talking directly in a way I would have felt awkward to ignore. I noticed roughly in order: a complexion compatible with playing a race card, a jean jacket, some kind of dark shirt beneath, a neck lanyard of the kind worn by government employees and contractors, clean shoes and a generally kempt appearance.

He was talking somewhat rapidly, though politely, and, one might say, smoothly. He works at the the Department of Homeland Security or some such agency. He was driving his wife and kid and hit a curb and got a flat tire. He doesn't have a credit card, or "they" don't take them, and he needed some weird anchoring number like $18.97 to something something resolve the problem. His name was something something and he would give me his information and pay me back tomorrow he was coming down the road and made a U-Turn and struck the curb (here seeming to gesture at E Street, and my mind processing between the fact that E Street is one-way but yes sure enough there are tire marks on the far curb) and the wife and kid

So I interrupted to ask something like "So what are you trying to do?"

I am a legitimate and fair mark because to give my mind a moment to process I interrupt the patter, but only to ask him for a boatload more patter. He had "currency" and pulled out a small wad with a twenty on the outside and says he is short for the tow and to buy a spare tire. I was already hooked, he knew, but he still had to reel the fish in.

I had stopped walking to listen, and now turned back the way he had looked when talking about his stranded loved ones, and I said "Let's go take a look." This suddenly was not practical, he was actually parked in front of something something monument and something. I am getting a little annoyed now typing this but want to put it down for science.

I was long since decided on what I would do even though my mind was in some complex eigenstate on the truth value of this guy's proposition, so I walked a few steps to put my drink down and told him I would give him my contact information. For some reason that seemed like the better way to do it. I pulled out a vanity card which won't get him more than my cell number, name, and if he is clever about WHOIS my previous home address. I passed it over and then the banknote and nodded and probably shook hands and he said I would be hearing from him and I said "That's great, good luck" and before or after that he said something like "okay I can get the other four pretty easy now" like some kind of attempted upsell.

There is some consolation in the fact that I didn't put on a convincing display of credulence and could plausibly have felt sorry for a random dude who resorts to trickery to score lunch (or other) money. He had a cell phone in his hand at some point, another data point that may or may not mean anything.

What I did that was good:

• Suggested my own method of verifying one of his claims.

• Turned a bit aside while retrieving the ransom, to make a smash and grab operation marginally less obvious.

• Did not loan him my credit card or cell phone or get into any enclosed space with him or give him much more than what a lesson in street smarts might plausibly be worth.

• Gave a needy person money?

What I did that was bad:

• Became utterly mesmerized by his patter while trying to understand him and his situation.

• Failed to recognize that he immediately dissuaded me from gathering intelligence that would bolster his story.

• Gave a conniving jerk money?

Action items for future encounters:

• Slow down. If you are in a hurry, grunt an apology and move on. If you stop to talk, deliberate. Any time pressure from the other side smacks of tactics.

• Remember the lesson of the Wason selection task. Disregard confirming evidence and seek disconfirmation. The scammer selects only information that is consistent with genuine need, and this information is useless in making the important determination of honesty.

• Tune out the patter. Ask for clarification. Don't rush.

• Think of some piece of evidence and ask for it. Ask to see the called number log on his cell phone. Ask what kind of car it is, then ask to see the car keys. Something.

• Recognize high-risk cliché scams. Car trouble, but no visible car. Short on money, need an uncomfortable but not worth calling authorities amount to pay some urgent need.
