I don't think keeping rental low will raise the quality of
hawker food.
More likely low rental would mean the lousy hawkers can
survive and continue to dish out their so so food.
Too high a rental, and they can't make a decent profit, which
would then defeat their purpose of going into business in the first
place.
The balance must be there.
The hawkers must take steps to improve their food, and
charge a premium for it. Or go bust.
An eating place near me have upgraded its premises, and must
also have upped the rental. The average price of dishes there
is now $3.00.
I see the Malay stall now can survive. It serves better
qualilty Malay food at $3.50 to $5.00. The Chicken Rice
stall will be a casualty soon. It sells $2.00 quality chicken
rice for $3.00, sure die one. No more mama rojak stall, selling
roti prata and mee goreng because this type of stall never improve
one.
Bad point about increased rental is kopi/teh lousy as hell,
increased from 80 cents to 90 cents, and must queue for
it.
