It seems that they are changing bosses at the Immigration Office. The old one is gone, and the new one has not started yet.
So, until next week there is nobody there that can sign a Certificate of Residence. This is the form you need for getting a drivers license or registering a vehicle.
Only the boss is authorized to sign them. Oh well, this is Thailand.
"The true secret of giving advice is, after you have honestly given it, to be perfectly indifferent whether it is taken or not and never persist in trying to set people right."
