Just in, this alert from Paul at Coffee at the Heights (WSB sponsor):

Thought that we would put it out to all the West Seattle businesses, we took a counterfeit 20 today, about 12:30. Description of the guy is 6’1″ dark complexion, slender build, 3 Inch afro that was kinda messy, appx 30-35 years old, with a slight accent. Wearing yellow, green and blue striped oversized polo with faded light blue baggy jeans. We don’t know if he was on foot or in a car, but he headed out of our shop north on 35th Ave SW. Just a word to the other business owners out there.

To elaborate on the location, Coffee at the Heights is in the building on the northwest corner of 35th/Webster (map).
