To get a wider view of the Bushwick social engagement action, I talked to a happening bartender who watches people interact socially for a living. I chose Sally Courtois, a bartender at the bar Post No Bills at 253 Bushwick Avenue. Sally likely gets told she reminds people of Scarlett Johansson. She’s been a bartender at various bars in the neighborhood for the past 3 years. I picked Sally to interview because she seems to be a strong, independent young woman with an equally balanced view of men and women. I spoke to her for quite some time before asking her specific questions for this column.
