If you pay in Thai Bhat they want 1,500Bt, which is about 47$ rather then 25$ with current exchange rates. Where I went, Chong Jum / O smach border crossing, they wouldn’t take US$ and insisted on Bhat.
There is also a turn around fee ( if you stay less then 24 hours in Cambodia) of 300 Bhat for an exit stamp. This fee is a scam and not an official fee, and if you stand your ground and refuse to pay more then likely you don’t have to. I just pay it so can get out of there quickly.
