A keynote for Knowit in Copenhagen, with no fee charged
Tarry Singh flew to Copenhagen on 28 February 2019 to keynote a Knowit event, spoke to a hall of about two hundred, and billed the client nothing.

The day started at 05:53 on 28 February 2019, on the first train out of Assen. Schiphol at 07:57, then Kastrup. A Dantaxi meter ran from the airport depot on Ellehammersvej from 13:39 to 14:01, 13.9 kilometres, and stopped in central Copenhagen.
The first photographs from inside the room are stamped 14:09. They show a hall with a wooden floor, one wide screen and roughly two hundred people seated in it, most of them in office clothes. Two Knowit pull-up banners stand either side of the stage. One reads Intelligent business. The other reads Passion for technology. The programme ran in Danish, and the slide on screen when the shutter went belongs to another speaker. It is titled Systemlandskab.
Tarry Singh was there as the invited keynote. Inside deepkapha.ai the engagement was filed under AI philanthropy, with no consulting charge to the client. The only money that moved was travel: two train legs at 14.53 euros each and two Copenhagen taxis at 42.90 and 41.05 euros. The claim came to 113.01 euros and went through Finance and Operations.
He left the next morning. The second taxi receipt is timed 10:58 on 1 March 2019, DKK 328.00, paid in Kastrup. The train out of Schiphol reached Assen at 16:26 that afternoon.
Photography from this keynote is limited to two frames of the hall.
