What are the chances of being denied entry to Thailand while applying for a B visa from a Burmese consulate?

Hello,

I have a question. I was in Thailand previously and had a mix of Ed visas, B visas, and tourist visas. I got denied entry at the airport in Bangkok last August for not having 20,000 baht cash on me but then entered by land and was in Thailand until about March. I am now working in Burma and have a B visa here (way easier!). I am planning on flying into Bangkok to get a new B visa from the Burmese consulate in Burma. I will have my flight back to Yangon booked and a letter for my Burmese B visa. I am planning on being there for a week. I want an in person visa and not an e-visa because if I get three b visas at the same consulate in a row I can get a one year B visa (weird Burmese rules). Do you think there is a high chance of getting denied entry when entering Thailand?

Thanks,
