Looking rich and being rich have different feel.

If today you found out you have only RM100 in your account, you try walking in Pavilion or Star Hill, you will suddenly feel why you are even in that place.

Put the same scenario you have RM 10000, be at the same place, you suddenly found you have options and choice.

The problem of making people think you are rich is it will take a lot more mental effort to cover your deficiencies. That we know as conman.
