yes I did, but the return date of my ticket didn't seem to be an issue. This was Vancouver, Canada and I can't speak for all other Embassies which processes visas.
I applied on line for 60 day visa. My flight itinerary was for 5 months. They don't care about the return date, but you need to have a two way ticket. I spoke with the embassy and they confirmed they don't care about the return date. The lady said people can change flights at any time...
I did it on a tourist visa two years ago. I provided proof of residence from a condo hotel and went to immigration for a 500 baht letter. Took the paperwork and my passport to the Bangkok Bank at Bluport and opened an account.
