I havent found automatic coin counting machines in CM, so my routine is:
keep a few small ziploc plastic bags in a bowl for each type of coin. all the copper satangs go moxed together.
- use 10฿ for laundry
- use 5฿ for coffee. local shop at the corner always wants 5฿ coins
- 2฿, 1฿, and satangs all go back to buy things 7 eleven where they came from (in organized small bags) Most other shops, I use mobile payment which is not accepted at 7-11. So, most of my coins come from change on cash transactions there anyway.
