No, I haven't been back to that course, which is 10 minutes from my house.
The rude woman in the bank didn't work there, so I still use the account.
More recently, I asked to borrow some money from another bank just to see if I could. After asking for my passport and getting my Thai ID card, the teller said they had better check with headquarters. When she got off the phone, she said yes, but you need to show your Work Permit!
