Can I extend my stay in Thailand again after a tourist visa extension?

The original poster is concerned about reapplying for a tourist visa extension in Thailand, having already entered on a visa exempt basis and extended their stay once. Responses from the community indicate that while it is generally at the discretion of the immigration officer, many believe that a pattern suggesting tourism often results in smooth processing. There are mixed opinions about the risks and procedures, with some emphasizing the importance of having proof of onward travel.
