Actually I think their current process is fine. Buying a house is not the same as buying vegetables at the market or booking movie tickets. They need to walk through the financial and legal implications before you make the decision to commit to the option fee. If we follow your process to let everyone book first, you would see less dropouts during the selection. More would then lose their option fee and be barred for a year, and those that could have selected better units because of drop outs don't get the option to do so.
If you were able to comprehend what I wrote, you would then understand that it merely increase the efficiency of the selection process. Whether you agree with it or not, that is your prerogative but I think it is pretty presumptuous of you to assume that I treat buying a flat like masak masak. No where did I suggests that financial and legal implications should be treated lightly since during the appt to pay the booking fee, buyers will go through the same financial process as of now where their financial status is assessed accordingly.
