Anything above 35 is good rate historically. Or if you prefer drainbow advice “man US dollar going to crash to almost zero soon due to new world order, it’s over for fiat currencies best invest in crypto buy a lambo”
out of Thailand anywhere. Google throw away ticket a lot of people have used them. If you are arriving on 30 day visa the flight has to be within that time period. Airlines / immigrations don’t entertain people’s plans about getting long stay visas they just follow back and white. Extremely unlikely you will be asked for anything when you arrive in Thailand if you haven’t got history of visits.
pretty sure I stated that when referring to “unique” but you mostly find they cut their fees to zero but not the Thais atms fees. Cash is also a good option for people wanting to get the best rate possible.
