absolutely correct... so many people think "i make kaya toast only 80cents why atas kopitiam can sell 5RM?!"

real life example here for you.

opened a Juice shop for the past 6 months as my side income.

Cost in general:
Rental 6k
Manpower 5k
Raw material 3k

Gross per month in general: 20k-25k

this is not including how much i've put into my renovation (80k)

So nice to do or not you decide yourself. but generally i feel its a pain in the ass. as its a side income i have nothing to complain. but as a main primary job, wouldnt suggest doing it for me PERSONALLY.
