I have only been to Otakon twice, but whenever I had a question or needed directions, I was always given a response in a friendly manner or was directed to someone who could help me. I arrived thursday evening in 2012 right after the huge thunderstorm and I got my badge within 10 minutes.
I have to say, I do question why it is necessary to have like 10 million badge checks, even for when you are leaving the artist alley. Either way, i think that a lot of the time, people dramaticize their stories because they are getting more upset over something that really wasnt a big deal. As for reports of staff "yelling" or being curt, you encounter that at any big con, because, hey, that staffer probably had to say "dont stand in the middle of the hall" to 75 other people before he/she said it to you.
On hiatus until 2015.
