Do what the few proper commenters suggested - stack them into 10's. Use tape. I exchanged some at a 7eleven before and it was easy. They have a quick way of counting them. Really, it's so much easier if you tape them.

Don't listen to what the rude people commented in here. Most of them won't even give coins to the poor people around. It's your money, you earned it, use it the way you want it and do whatever the hell you want with it. 😉😇 Good luck!

Did you apply for the Thai Pass with hotel reservation, airport transfer + RT-PCR upon arrival and ATK for Day 5?
