I proposed an idea to speak at AWS RE:invent in Las Vegas, so I travelled domestically to speak. The event gave me a free ticket, and I was not paid to speak. The event assisted with part of my travel and accommodation. My employer paid all of my travel expenses, and I was working while speaking at the event. It took me 5 days to prepare for my 1 hour speaking slot, and I had a mostly good time. I'm a man who has been speaking for 8 years. This was a for profit event.
