Cannot Lah !!! - The Harley Davidson Story

Spent most of last weekend at this pub called Handle Bar…
Nice place.. biker theme. So there were lotsa biker dudes with Harleys and other big bikes
Now the thing is.. When you see a guy on a Harley, you have an image in your head of what he'd look like and act like… you'd think he would be this macho guy n stuff.. But I forgot that this is Singapore !!!
So we're having a drink and some of these guys are standing next to our table..
And they're leaving and this was the conversation:
1st Harley Guy: "How bout we do xxxx and then xxxx thing"
2nd Harley Guy (who is this hunk of a guy replies in true Singaporean style): "Cannot lah !!!" …. (I didn’t hear what he said after that.. I was stumped on big macho guy owning a Harley saying those 2 words)
Oh Singapore Singapore !!!!
