I proposed an idea to speak at EuroPython in Bilbao, so I travelled internationally to speak. The event asked me to buy a ticket at full price, and I was not paid to speak. The event did not pay for my travel and accommodation. My employer did not pay my travel expenses, and I took unpaid time off to speak. It took me 3 days to prepare for my 45 minutes speaking slot, and I had a great time. I'm a man who has been speaking for 5 years. This was a not for profit event.
