if u prefer me to demolish yr whole theory, i will be happy to
do it!!

If you studied geography in sec sch, you should know that going to
JB to shop isnt really cheap. They know that Singaporeans always go
there, thus they jerk up the prices.
So basically, things are almost the same price as here. Cos its
part of their boost to increase the revenue from tourism.
And of course, we are considered tourists.
u just need to go further up like 5 km
inland into JB, u will find things cheaper than those at the
doorway of the causeway!
If you go to major tourist attractions, then you are less likely to
get robbed. Or if you want, you go to those supermarkets or malls
that are inside which are frequent by locals and not
tourists.
Malls that everyone knows are for tourists will of course have
higher number of robbers there targetting.
Can u make up yr mind on whether u will
want to say that tourist attractions have greater tendency of
robbery occurence or not?

If you are a robber in Singapore, and you want to rob tourists,
where will you lurk? Orchard Road or Tampines Mall?
how many times have u heard of robbery
occurring in orchard road this year?
such a lousy example u trying to pull 
u talk about geography, so that what's i am telling u
if u can't make sense of what u trying to express, try not to
express otherwise u r making a fool of yrself
