Usually they waive the first 24 hours period but not 2 full days. Pay the fine 1,000 or do an extension for 1900. It's irrelevant why it happened for immigration.
I know where you are coming from. When I was there last I saw a sign in McDonald's saying tomatoes and lettuce salad and when I ordered it they said sorry sir no more tomatoes left. I have never ever heard that anywhere else in the world. Why is there so little salads around?
I had a 60 day tourist visa and I extended it last week. In and out the local immigration office within 30 minutes. Cost 1900 baht. If you need more after the extension then you need a border run.
