you'll have to bounce unless you want to get into a longer-term visa

Yeah 2000 baht fine but also you have to sit around at immigration while they deal with that. If you're in BKK that's another several hours in the immigration office. Plus you burn up more space in your passport with a big red "DIDN'T DO 90 DAY" stamp. The stamp doesn't really hurt you (although it certainly could in the hands of the wrong immigration official) but typically it doesn't matter. However it's going to burn another 0.5 to 1.0 pages in the passport. And the sooner the passport fills up the sooner you spend ANOTHER day at immigration moving stamps around.

So basically unless you love spending time in the immigration office it's easiest to just keep it up to date.

Every bank branch will be different. If you can take a Thai person with you.

the schedule follows your entry. It doesn't matter about your extensions it's based on when you entered, and if you leave in the middle of your visa and then reenter under the same visa it will reset your 90 days to 0 and it counts from that entry.

Visa extension date and 90 day report date are unrelated.

if you got your stamp and it's correct you will be fine.

This is Rebels trying to overthrow the Chinese puppet government, right?
