Can I use a bus ticket to Laos as proof of onward travel for a multiple entry tourist visa application for Thailand?

The user inquires if a flight ticket into Thailand and a bus ticket to Laos for their exit, 59 days later, can be used as acceptable proof of onward travel when applying for a Multiple Entry Tourist Visa (METV). Responses indicate that showing the bus ticket should be acceptable, but the final decision rests with the consulate, which may request additional proof if deemed necessary.
