Out in the Strand, a Filipino artist called Chito Salarza-Grant was showing off his Thatcher hat.
It was a fantastic creation, an elaborately wrought cube whose sides bear images of Thatcher's face, backlit by flickering holograms. On the crown a miniature supermarket trolley, in homage to her birth as a grocer's daughter, and Union Jacks.
Salarza-Grant admitted he wasn't around in Thatcher's heyday - he was studying art in Manila - "but I feel she empowered generations of women around the world. I like her because I'm gay and I like how tough she was in a world dominated by men."
An elderly passerby, who had stopped to listen, turned away in exasperation. "Good riddance to the old bag," she muttered.
That brisk exchange set the tone for the funeral of Britain's first woman Prime Minister: great admiration, extreme condemnation, lots of voices and display, plenty of eccentricity, and absolutely no sense of a nation united in grief.
