If you are boycotting for your own conscience, then good for you. That's what I have chosen to do, and, no, I don't think it will affect the mall's profit margin.

But I agree with no merci, I seriously doubt the other malls are much safer. Although I have hear from reliable sources that the both Landmark and Hyatt were built to a better standard, and the layout and size is better for evacuation. But whether or not codes have been followed since construction is anyone's guess.
