David is right. But Mixed rice stalls can earn much higher, about RM 8,000 to RM 10,000.

One dish typically costs RM 5.00. One table can accommodate 4 customers. There are 20 tables in a typical medium-sized restaurant. The peak hour lasts for 2 hours. The restaurant opens 26 days a month. You do the math and take 50% as the profits.
