ive operated a burger stall during my university days over a decade ago under koperasi. easily about 200 buns a day. average price is RM2.5/burger. that is in university campus. and we share among 4 others + koperasi cut.. average 1K income per head depending on total sales. 4 hours work per day. but this is university campus lah... customer flow non stop. preparation for burger stall can be done during opening hours itself.

somewhere 6 years ago, my business doing very badly. just to earn a bit extra i took part time flipping burgers at night. average sale 100-130 buns a day. store making average sales 15K/month. the owner have 3 stalls and usually hires 2 workers per stall.
