Recently there was a post about Con Ed impostors.
This happened today in our building! My wife spoke with him briefly and very tersely said she wasn't interested. I got home shortly afterwards and when she told me what happened I searched for him, but he was already gone.
Please be aware that this is going on and tell your neighbors. We have friends in Astoria who were just burglarized recently. This will only stop if we look out for each other.
