Will I have problems re-entering Thailand with a history of multiple tourist visa entries this year?

The user, who has entered Thailand twice this year on a tourist visa for two weeks each time, is concerned about potential issues when re-entering in December. Comments suggest that the user should not have significant problems, as multiple entries are generally permissible. However, final entry decisions are at the discretion of the Immigration Officer. It is recommended to be prepared with proof of funds, onward travel, and accommodation details upon entry.
