Cheap or Expensive? Economy Rice

Someone in my shop promoting one of the homemade economy rice and keep asking us to buy it as our lunch. A pack of rice consist of 3 dishes cost us approximately RM 3.50. After I did some simple calculation, I found it ok. I can get 26 days of lunch with only RM 91. But still, I think(IMO) I can, and I should save more money for other expenses. So I told the one who promoting this lunch that I only need 2 dishes for the rice. She replied me in a very haughty way that she cannot provide me such service. So, I ask her if I can get a RM 3 economy rice from her. Of course, the answer is NO. She even said "Ai Lai, Mai Suak." Meaning, have it or leave it...
I can't stand such attitude because I'm pretty sure I can get something similar with lower price.
After few days of hunting for delicious and cheap economy rice, I found out one old stall, that I used to eat while I'm still a kid. I walked in and realize that they did not change the style of their business. They serve curry chicken, curry fish, soya bean saucing pork, fried egg, stew duck, vegetables and some typical dishes. One thing that caught my attention is that they do have order-and-cook service. Just like a home-cook restaurant.
Look at the rice economy rice below and guess how much is it?

It's just merely RM 1.80!

It is approximately RM 2.60 if I get 2 pcs of chicken + vegetable + potato.
With such price, I only spend around RM 2.20 per lunch and after doing some simple calculation, my expenses drop to RM 57.20. A significant RM 33.80 per month of savings!
Yea, I know most of you will say it's not a big deal, but you know what? I can save RM 405.60 per year... hahahahaha.....
Anyway, blogging for fun right? Take it easy~
