I also seem to be the type or person that con-artists pick as a likely mark. But because Delaware is pretty small state, people tend to work the same areas over and over. Back when Amy was taking the train in a lot, I used to get hit up by the same well-dressed twentysomething at the Wilmington Train Station. He didn't remember me, but I sure remembered him. He doesn't take it too well when you inform him that he gave you the same sob story last month. Especially if you say it loud enough that the whole train station can hear. Other people have tried to work me in the Newcastle Walmart parking lot as well. They tend to hoof it towards their cars when you tell them you've heard it before from them.
The weird thing about all of this is that regular people didn't tend to bother me on the street. Even as a scrawny college student people ignored me or got out of my way. Perhaps I just don't look angry or purposeful enough anymore?
