I was invited to speak at TechDays in Den Haag, so I travelled internationally to speak. The event gave me a free ticket, and I was not paid to speak. My travel and accommodation was fully covered by the event. My employer did not pay my travel expenses, and I was working while speaking at the event. It took me 2 days to prepare for my 60 minutes speaking slot, and I had a mostly good time. I'm a man who has been speaking for 10 years. This was a for profit event.
