the main problem is that people forget to switch off singlish
when they speak to people overseas.
no one understands "lah, lor, makan, on the light, ear
already?"
u don't need to fake an ang moh accent to ask if someone has had
his lunch.
kopi, your post reminds me of this Aussie man who proudly
boasted to me of how he had to travel frequently to Singapore for
business LAH and then he started to inject LAH into every bloody
sentence he said!
I got a bit irritated after about 10
mins of non-stop Lah'ing, and all from him, not a single one from
me.
So I told him politely, "Hey, mate, you
can ease off on the 'lah's' because I already get it that you
appreciate Singlish." (That was the my polite way of saying, "Shut
up, you lah'ing idiot!" 
He persisted in lah'ing all the way so I just let him drone on
and on and my mind went elsewhere.
Then when he asked me for a date, guess if
I accepted or not.
