Do you have change?

In Singapore, if people ask you "Do you have change?" they really wanna ask you whether you have smaller change for their note. For example, a $2 note to exchange for 2 $1 coins.
But here, if people ask you "Do you have change?" They wanna ask if you have spare cash to give them.

Yesterday, I was going to the supermarket.. at around 8pm. I wanted to buy orange juice. So..I headed towards Provigo..

On my way there, I saw some people (a few more than usual) asking around for money..
Then there was this AM guy who asked everyone near the traffic lights "Do you have change?"
Sensing someone behind, he turned around and asked "Change?"
After seeing me with my "chinese" face, he turned away and continued asking other passerby for change even before I replied "no."
