Can I apply for a second visa extension in Thailand after my initial 30-day extension expires?

The user, a German national, is seeking advice on whether they can apply for a second extension of their visa after a 30-day extension has been granted. They mention needing to stay an additional 4-5 days beyond their extended stay and inquire about the process involved in potentially obtaining a grace period if their extension application is denied. A comment clarifies that if they apply for an extension they are ineligible for, they may receive a stamp indicating a denial along with a 7-day grace period to leave Thailand, starting from the application date, suggesting they should apply on their last day.
