The problem is all these shops main targets are the foreign tourists.
The tourists will not stay for long, so they do not have the time to scout around.
And not forgetting those who never do any price researches and kena chop till jialat jialat.
Even if we boycott these shops, as long as they have a few walk in customers everyday, they can still survive.
guess you are right.
i think these kind of stuff will never stop...
