I was invited to speak at DaFED in Novi Sad, Serbia, so I travelled internationally 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 working while speaking at the event. It took me 1 day to prepare for my 30 minutes speaking slot, and I had a great time. I'm a man who has been speaking for 4 years. This was a not for profit event. Also, The event is free to the audience and the organisers took care of me so dearly, it was outstanding!
