I NEVER go to the mall but went once at Christmas time with a friend. In and out, one store stop but the store was in the middle of the mall.
The mall was full of nothing but Mexican families and youngish Mexican girls.......all carrying numerous bags from different stores, all speaking Spanish.
I told my friend......looks like the only ones with money are the illegals.
Illegals really do have more free cash to spend than you do. Your impression was accurate.
