You might see this sign by a light switch. The first word is handy as it means "do not". In Thai it says "yaa leum bit fai" which translates as "don't forget to turn off light". Actually "bit" also means "close" which is why a Thai will say "close the light" in English.
อย่า ลืม ปิด ไฟ (yaa leum bpit fai)

Thai Signs: Toilets for Monks
I saw this sign at a temple yesterday. There were a row of toilets but on one door there was this sign. It says "hong nam phra ajarn". Members of the public cannot use it as it is for the monks. "Phra Ajarn" is a teaching monk.
