Thai on the street (public institution)

This means a branch of public institution in Bangkok. Can you read this? Maybe you sometimes go there if you live in Thailand

prai sa nii: postal service, post office

พระโขนง

phra khanooŋ: Phra khanong (BTS Sukhumvit Line)

Staff of post office in Bangkok normally speak English very well. I feel using domestic postal service in Thailand is a bit risky, but if you want to send something from post office in Bangkok to your home country, it might be OK
