This is purely my observation as a Chinese ethnic, on stalls operated by Chinese ethnic. Chinese New Year had came and gone, and to the Chinese ethnic, this is a second new year. And as expected, the price of food and drinks had went up, again. That was somehow the question which your parents will usually ask the first thing they visited their local haunt: drinks price got increase ah?
My time in Singapore may not be long, but I was surprised by the fact that the price of hawker food remain low in general, in comparison to Malaysia, even though the former had to import their raw material. From what I heard, an increase in Singapore's hawker food price had not been major for a long time (of course, I could be hearing from the wrong source).
