I proposed an idea to speak at NetConf.UY in Montevideo, so I travelled internationally to speak. The event gave me a free ticket. 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 5 days to prepare for my 2 hours speaking slot, and I had a great time. I'm a man who has been speaking for 8 years. This was a for profit event.
