I proposed an idea to speak at DrupalCon in Los Angeles, so I travelled domestically to speak. The event gave me a free ticket, and I was not paid to speak. The event did not pay for my travel and accommodation. My employer paid all of 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 great time. I'm a man who has been speaking for 5 years.
