Non-Standard English

Proof that "handphone" is not Standard English. From the Boon Lay library:



But, I would map "Please turn off your mobile phone" to "Off your handphone leh" instead of "lah".

The comma before the "lah" seems quite curious too. In any case, "Off your handphone lah" in proper English would be more along the lines of "In that case, turn off your mobile phone".



Another typical Singlish pharse, which omits the subject. This can be done when the subject of the conversation is obvious, otherwise the response would very well be "What thing what time start?".
