I was invited to speak at a GDG events, so I travelled domestically 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 unemployed when I spoke at the event. It took me 1 week to prepare for my 2 hours speaking slot, and I had a great time. I'm a male who has been speaking for 3 years. This was a not for profit event.
