not really....u got this fact incorrect....one of the highest sales volume is selling fried chicken...bck to few years ago...yea...one ngiht can easily fetch may be3k-5k....but well lok this the situation now and one can knew night market's hawker suffered like hell....due to

-inflation (everybody saved like hell....)
-Franchise competitor (they r great competitors and areas like sri rampai with lotsa unis around....they will be the winner)
-highly competitive market (need not to be explained)
-Rain (this is the worst scenario which happened and well...it happened almost everyday nowadays)
it may be true...but well...u r gonna suffer more than anyone or anytime u'd been suffering in ur life time.....u will sacrifice ur family life, social life and private life due to the fact that u r gonna work from morning (to get thee stocks, to get things done....run from KL to puchong to kajang juz to get ur stocks) to afternoon(u will wanna get a short nap) and u work in pasar malam from 3 to 12....Bingo.... I would wanna say...u will be richer than most of ur frenz in 1 years time and probably be a millionaire if u r not married and u manage ur finance well. but u sacridice alot alot alot.....yea....physically...and mentally... i start working since 13 years old in night market and i sell fried chicken from someone....i woke up at 8 to wash the 0 celcius frozen chicken with abre hands.... take and mix those chicken ( is so easy in words but they weighted at least 18 kilogrammes per packet and i took them alone) attach them into bamboo sticks (where scars and bloods pop out like no end when the bamboo sticks cut on me) boilked the chicken with honey (where i was often 'hit' by those 100 celcius honey) the whole process ended  at 12 and i gotto arrange those chickens and fish balls.....it took us quite long....until 3 o clock then we go and work and shout at the night market until 12 o clock... then go home....

u will be a millionaire but u paid for it.
